Q Doc, I have to deal with Krazy Glue quite a lot in my work. People are always playing silly tricks with it - for instance, putting it on toilet seats. This scares me. What can I do if I get some on my skin?

A Practical jokes involving Krazy Glue are, I believe, illegal - and the cops would regard them as a form of criminal assault.

If the glue sticks your skin to anything, it is important NOT to try and pull away, since that could tear the skin. Instead, wash the area with warm, soapy water, which will start dissolving the glue. Then use some nail-varnish remover, which will get rid of it after a while.

Q Doc, I guess I am what you might call a slightly nervous young guy. I have always been rather shy of women, and it was a long time before I could pluck up the courage to ask one out.

But now I have found a real nice, pretty girl who is the same age as I (21). And to my surprise, when we were only on our third date, she invited me to take her to bed. Everything has been great, and we get on real well. I love her.

However, I am a little worried about one side of things. She likes me to 'turn her on' for maybe half an hour before she allows me to have intercourse. Fortunately, she is a little more experienced sexually than I, and has told me some things I can do to get her excited.

But I have got quite anxious about one particular thing she wants me to do. A few nights ago, she asked me to stimulate her with my finger. Doc, it may seem foolish to you, but I was a little frightened by this request. I was afraid that I might hurt her, or that maybe my finger might somehow get 'stuck' inside. I have heard my friends talk about such a thing. So I didn't do it. She just laughed, but I know she was disappointed in me.

Do you think I should try again, Doc? Is this what a lot of women want? Also, just what is a guy supposed to do, once he has put his finger inside the girl? I have no idea.

A You must try to quit fretting over all this. Sounds like you have a real nice, caring girlfriend who is very patient with you in bed. Incidentally, I hope you are using some safe form of contraception with her!

Let me assure you, your finger will NOT 'get stuck' inside her! If you read last Saturday's Gleaner, you will see that I advised another inexperienced younger man about how to stimulate the woman's clitoris - which is OUTSIDE the vagina - with the fingertips.

You ask whether a lot of women want this, and the answer is 'yes' - many of them do. There are exceptions to this rule - a number of females are afraid about having anything put inside the vagina.

Why would women like having this done? Well, it is because the female human body is so constructed that its owner gets pleasure from having something inside the vagina. If she is relaxed and feeling romantic, the presence of something inside the vaginal tunnel will stimulate her erotic nerve endings.

There are three things that are commonly put into the vagina to give pleasure. First of all, of course, there is the penis. Second, there are sex aids, called 'vibrators'. And third, there is the partner's finger.

Before using your fingers, it is really important to wash your hands! After all, you don't want to insert germs or dirt into your partner, do you? Yet an amazing number of men neglect this simple hygienic precaution, and start 'fooling around' with a girl but neglect to wash their hands first. Also, ensure that your fingernails are carefully trimmed. Popping a jagged nail into the vagina can be disastrous, as it may cause bad cuts.

Now, when your young lady is completely relaxed and happy, it is OK to slip one finger inside her. Try to make sure that your finger is well lubricated so that you do not cause her discomfort. Once inside, there are two main things that you can do with it:

Move it gently in and out. This 'mimics' the action of the male organ in the vagina, and so is appreciated by many females.

Bend your finger, so that it stimulates various parts of her vaginal walls. This stretches the muscles of the vagina and stimulates the erotic nerve endings.

Q I am a guy of 20, and I just lately started having sex with this older lady. But I can't 'stay long' during sex, Doc. I never go beyond two minutes. She is cool with it, because she says 'it happens to a lot of males' in her experience.

What can I do, Doc? I read on the Internet that flexing my 'PC muscle' would help.

A I do not think that contracting your PC muscle would do much good. As I am sure you realise, you have a degree of 'premature ejaculation', which I have mentioned in this column before, since it is so common in young guys.

Fortunately, you have an understanding and cool lady partner. I suggest that both of you try out the 'Masters-Johnson grip', which you can find described on the Net.

If she applies this grip regularly to your organ over a period of two to three months, there is a good chance that you will be able to last much longer.

Q My boyfriend is always telling me that if he rubs my breasts, I should discharge. Is this true, Doc?

A No. Admittedly, there is a small group of women - believed to be less than 15 per cent - who can get orgasms by having the nipples stimulated. But most females cannot do this. So pay your boyfriend no mind.
