Q Dear doctor, I am a 19-year-old sixth-form student, and still a virgin. I am under such pressure to have sex that I no longer find school interesting! Yet my exams are only a couple of months away. But it is real difficult to concentrate on them when people are pushing me to have sex.

A You must pay them no mind! Your exams are enormously important for your career and perhaps for your whole life.

I would strongly suggest that for the next couple of months you should stop all social contact with the people who are pressuring you to have sex. Seriously, you must avoid going out in the evening and just study, and rest.

During the day, try and think only about the subjects which you are going to take in the exams. Pay no mind to 'peer pressure'.

Q My boyfriend of two years has a problem, and won't yield to my advice. I believe something terrible is wrong with his testicles. You see, doctor, one of them is extra large.

He says he has had that from he was a kid, and apparently his mother told him that he inherited this tendency from his father.

A Well, although testicular cancer is at its most common in young men, your boyfriend's medical history does not really suggest anything 'terrible'.

If this swelling has been present since infancy, it is probably some congenital problem such as a collection of fluid around the testicle. That is called a 'hydrocoele' - pronounced 'high - dro - seal' - and it is real common. Hundreds of young men in Jamaica have the same thing.

Please tell him that I urge him to have his testicles checked out by a doctor. The examination will only take a couple of minutes, and is not painful. It will set everybody's mind at rest.

Q I am a guy of 19, and I notice that when I get sexually excited my foreskin will not roll back. So it covers the head of the organ. Help!

A This is too tight. You need to take a little operation - probably a circumcision.

Q Doctor, I am a 22-year-old man, and my girlfriend is currently in the UK. She has emailed me to say that she keeps getting situations in which she feels she is about to pass out. Afterwards, she has to sleep. When she awakes, the feeling has gone.

Why is this happening?

A Although there may be nothing serious wrong, this young lady does need tests for epilepsy. That should not be difficult to organise in England, through a family doctor.

Q Doctor, I am female, 19, and I am not a virgin. Well, I am fretting because I have seen this whitish 'slime' on my panty. And I don't know what it is. Please help me.

A Please do not fret. I am sure that this problem can be solved.

A lot of young women are concerned about moisture emerging from the vagina. However, in many cases, there is nothing wrong at all. Let me explain.

First of all, it is normal for teenage females to produce a certain amount of fluid, which will usually make the panties a little damp, or even cause a stain on the underneath part of the garment. I am talking here about natural, healthy vaginal secretion. It is just a sign that everything is OK inside.

It varies in colour and texture at different times of the menstrual 'month,' being sometimes clear and sometimes a little cloudy or even whitish.

It also increases a lot in amount if the girl thinks about sex, or is sexually stimulated. This is because it is supposed to act as a sort of 'lubricant' when intercourse eventually takes place.

You should remember that normal secretion is not odourless, as many young women think it should be. No, it has a distinct aroma, which varies at differing times of the cycle. Females are not usually all that keen on this aroma, but biologists say that its function is to attract the male.

However, that vaginal secretion should not be several things! It should not be green, yellow, looking like lumps of white cheese; associated with an itch, associated with pain or discomfort, blood stained or brown.

Taking the above points in turn, I must tell you that:

A green discharge usually indicates infection; so too does a yellow discharge - and in this case, the infection is often with the little 'bug' called 'trichomonas vaginalis', similarly, a thick white 'cheesy' discharge usually means an infection - usually with the thrush fungus, also known as 'candida' or 'monilia; also, an itchy discharge is frequently due to the above-mentioned thrush.

A discharge which occurs along with vaginal pain or discomfort is often due to infection. Finally, a blood-stained or brown discharge usually indicates bleeding from higher up inside the genital apparatus - often from the cervix.

So what is this whitish 'slime' which you have noticed on your panty?

Well, if you don't have any itching or pain or discomfort, the probability is that it is just your normal vaginal secretion. However, as your email indicates that you have 'been with' a guy - or guys - in the past, it would make good sense to have a check-up, in order to rule out any possibility of infection.

This would mean that the doctor looks at your vaginal opening, then puts in a special instrument (a speculum) to let her see inside, and finally takes some swabs to send to the lab for testing.

I am pretty sure you have nothing to fret about, so do not be alarmed at the prospect of having this vaginal examination. Good luck.

Q I am a 16-year-old guy, and when I ejaculate the fluid is thick and 'jello-like'.

But when I watch porn movies and see the men discharge, their sperm is not like that. It is smooth and creamy. Is there something wrong with me?

No, you are fine. There is nothing at all wrong with the type of seminal fluid which you say you are producing.

What you have not realized is that in porn movies, the makers think it is so important to show guys 'coming' that they will gladly FAKE it. So they will use liquids squirted out from syringe-like devices. Among the liquids they use are cream and milk. So no wonder that you think it is 'smooth and creamy'!

Admittedly, there are times in 'blue movies' when you do see a male actor genuinely climaxing. And maybe you feel that what the guy is producing is smoother than your own ejaculate.

But it is important to appreciate that male seminal fluid varies a great deal from person to person, especially in the teen years. The thick type of liquid that you are secreting sounds to me to be totally normal for a young guy.

One final point: should you really be watching these misleading movies at your relatively young age?
