A. No, he certainly isn't! Any lump in the breast must be checked out by a doctor as soon as possible. This is particularly important after the age of about 35, because breast cancer starts becoming commoner at that time of life.

Please do not be lulled into a false sense of security by the fact that this lump is painless. In fact, cancerous lumps in the breast generally are pain-free in the early stages.

So please see a doc as soon as you possibly can. It is possible that your lump may turn out to be harmless, but you cannot determine that for yourself. You need medical advice now.

Q Doc, I am a man who started on Viagra recently. It works really well in giving me a good erection, but one thing worries me. Whenever time I take it, something strange happens to my eyes, Doc. For instance, if I look at the sun, it seems to be green! And if I turn my eyes towards the bedroom light, it seems like it is blue. What is going on, please?

A Do not fret. Everything is OK. One of the best-known side effects of high doses of Viagra is 'colour distortion' of vision. In other words, things may look green or blue to the man.

This curious effect passes off after a few hours. And, as far as we know, it does not do the man any harm.

I must add that very, very rarely, Viagra appears to cause real serious eye problems, but this is so uncommon that I have never seen such a case.

So please do not worry that after you have taken Viagra, you see things as a little green or blue. I suggest, however, that you ask your doctor to reduce the dose of the drug slightly.

However, she has expressed a desire for me to explore her G-spot. And I am very willing to do so, if it would help our marriage.So, what must I do? s it true that I would need some special instrument or vibrator, as a friend has told me?

A. No, you don't need any special 'equipment'.

Look: a lot of foolishness is talked about the female G-spot. If you check out 'G-spot' on the Net, you will find people telling you that it is 'the key to female sexual pleasure', which is not true.

You will also find that on the Internet there are lots of commercial outfits who are trying to sell you 'G-spot vibrators' and similar devices. But there is really no point in spending your money on these, unless you are rich!

So, what are the real facts about the G-spot? Well, the truth is that quite a few women do have a 'sensitive spot' located a couple of inches inside the vagina, and situated in the front wall of it.

Many of them like having this area pressed or rubbed, but others definitely do not !

So G-spot stimulation does not work for everyone. However, if a man manages to stimulate this intimate region, that may help his partner to reach an orgasm.

This climax may well be unusually intense and sometimes it is accompanied by a release of some female sex fluid.

Now, how can you stimulate your wife's G-spot?

Well, you cannot do it during sexual intercourse. A lot of men think that it is a good idea to get the penis to somehow rub against the G-spot while having intercourse, but that is almost impossible.

Nor can you do it during any kind of oral sex, because it is too far inside.

So the only easy way to reach the G-spot is with the fingers. Standard medical advice on how to do that is as follows:

The result of this will be that his fingertip presses against her G-spot area. If he has followed the instructions above, his wife will immediately experience an unusual and pleasant erotic sensation.

There may also be a slight desire to urinate.

In many cases, continued stroking with the fingertip will make the woman feel agreeably aroused. However, I must stress that some women do not like the unusual sensation which is produced. So, if your wife says 'Stop it! I don't like it', then please follow her wishes and stop.

A. That is real unlikely. However, I would like you to have the breasts checked out by a doc, just in case.

In general, unusual feelings in the breasts and nipples are NOT a symptom of cancer. Tenderness and soreness are more likely to indicate hormone changes, such as those which occur during the menstrual cycle, or in the 'run up' to the menopause.

Tenderness can even sometimes be linked to being in love, especially if the lady is very sexually excited.

As for cancer of the breast, that is real common, and the most frequent symptom is a LUMP, as I have mentioned above.. But ANY change in the breasts could perhaps indicate serious trouble, particularly in the over-35s. That is why I would like you to have a good check-up.

A. No. That is a common misconception. Although you can move your finger, it is perfectly possible that you have broken it.

So you need to let a doctor have a look at it. Depending on what he finds, an X-ray may be needed.

A. Yes, it could have been what is termed a premature menopause.

Unfortunately, that does happen to women sometimes, so that they experience the 'change of life' some 10 or 15 years too early.

The reason that should happen is not usually clear. But if you can afford blood tests, you could get a doc to check out your female hormone levels, in order to try to find out what has been going on inside you.
