I don't mind this, as it is quite exciting. Also, my previous boyfriend was kind of 'dull' in bed, and this guy is a big change from that!

But last week, something strange occurred. We were making love in a new position and suddenly I started to produce a lot of gas. It was very noisy, so I felt quite ashamed about it.

At first, I thought it must be coming from my bottom. However, after a little while, I realised that it was really being produced by my vagina.

It seemed to me that there were huge quantities of this gas. And when it came out, there was this vulgar-sounding noise.

I was so embarrassed. I did not say anything, and tried to pay it no mind. Much to my surprise, my boyfriend did not pay it any attention either. He just went straight ahead until he discharged.

Well, I hoped that this strange phenomenon was a 'one-off' experience. But it has happened several times since then.

Is there something terribly wrong with me? Why am I producing all this gas inside my vagina?

A What you describe is common. In fact, I have recently received several letters and emails from young women who have had the same experience.

What you don't realise is that you are NOT 'producing' this gas. It is simply AIR, which has been driven inside by your partner as he thrusts into you. After he has pushed it inside, it has to come out again - and that usually makes the noise which you describe.

I must add that the young man is not intentionally pushing this air inside you. He may be unaware that he is doing it.

You see, it is just a thing that happens in certain positions. It is most likely to occur when the guy makes love to the girl from behind, especially if she is bent forward. It also tends to happen if the male 'pulls out' for a moment before thrusting inside again. That gives the air a chance to get trapped.

Your new boyfriend probably paid no attention because he is experienced in bed, and has observed the same thing happen with other girls.

Also, young men are mainly interested in the idea of discharging, and so tend to give little attention to whatever noises may be going on around them.

I am sorry to tell you that there is no medication which can prevent this problem of 'vaginal wind'. Many women simply decide to ignore it.

However, you could try to remember which positions are likely to cause it.

Q I am a 17-year-old guy and I notice that my sex fluid looks different at different times.

Is that serious? Sometimes, it is thick and almost lumpy, and other times it is quite thin and smooth.

AYoung men often fret about the appearance of their seminal fluid. In fact, the liquid does vary in appearance at different times, depending on such factors as how many times you have discharged recently.

So you don't have anything to worry about.

QIf a woman experiences bleeding after sex, what should she do?

AIf the bleeding occurs only once, you can safely pay it no mind. You see, it is common for young women to get a little 'nick' or cut from a guy's fingernail, especially if he doesn't know a lot about female anatomy.

However, REPEATED bleeding is another matter. It means you should go to a doc for an internal check-up.

QI am a 20-year-old man and my penis is only six and three-quarter inches long. My fiancée says I am not pleasing her. Help!

AAs I have said on this page in the past, the average penile length is about six inches during erection.

If you are not pleasing your fiancée, that is certainly NOT because of the length of your organ.

Maybe you are not using good 'love play' techniques to make sure that she is satisfied. Or perhaps you are not showing the young lady enough romance, warmth, tenderness and love.

Why not ask her what she feels is missing from your sexual relationship?

QI think I am a little too skinny. I am female, 21 years old, and am only 110 pounds.

Are there any good 'rooster pills' on the market that I could take to put on weight?

AI would not recommend taking pills to try and put on weight. And 'roosters' are just a sort of herbal Viagra.

At 110 pounds, you are certainly a little on the light side. But a lot depends on what your height is - and also on whether your mother and father are slim people.

I would recommend that you go to a doctor to check if you have any condition which is preventing you from putting on weight, such as a hyperactive thyroid gland.

She will probably recommend that you slightly increase your intake of 'high-calorie' foods, such as cheese and butter, while maintaining a good all-round diet. I wish you well.

QWhen I attempt to put on a condom, I lose my erection.

Is that some kind of allergy to rubber?

ANo. This kind of loss or stiffness while trying to put on a condom is extremely common in young men. It has been called 'condom collapse' in medical textbooks.

It is simply caused from anxiety - in other words, fear that one will not be able to perform.

A good way to defeat it is to get your lady friend to put the condom on you. The idea is that she stimulates you with her fingers while doing so.

Good luck.
