If it's a constant fantasy about many women, I don't know. But if it's intermittent or about someone in particular, the best answer I've found is that perhaps the man is feeling possessive of the woman (or wanting to possess her, if they have no relationship). It may be a way of subconsciously claiming or marking her.
Most men to some degree will fantasize if they see an attractive woman and it is normal (just as some women fantasize about an attractive man) but, rule of thumb is 'look and don't touch.' When a man goes over that line and starts talking to the woman getting involved emotionally with her can be very dangerous and lead to a sexual relationship in some cases.
Obese women get pregnant the same way any other woman. Obese women should loose weight before getting pregnant. This will lower your chances of medical complications from weight.Depends on the woman. Some women who are really obese have hormonal changes so getting pregnant can be difficult.
When you say fantasize about woman the obvious reason come to mind that woman know what other woman like and the other reason is actually a question what do guys fantasize about woman! And by the way I'm not gay!! This question is very open to personal preferance, its exactly the same attraction as a male-female fantasy. Some like the way they look, or how they act non-sexually, or the way they perform an action, sexual or not.
It can affect your chances of getting pregnant, some drugs have a link with a mans fertility

The best place to get help in getting pregnant is from your Doctor. If you are having 'successful' sex and are not getting pregnant it could be that there is some hidden problem which is causing a problem, which your doctor will be able to help with and then refer you if you need further tests.
Each woman is different and for some it is harder.
A woman who wants to get pregnant faster should have sex more frequently, find out her ovulating periods to pinpoint the most fertile dates, step up sex just before ovulation, enjoy having sex and finally give it some time.
This vary a lot from woman to woman. Some go early into the menopause, some at age 29 even. Others do not until well into their 50's. As a general rule we can say that when you start the menopause and totally stop having the period, the chances of getting pregnant are pretty slim. For most woman this is after age of 45. Age alone however does not limit/rule out having babies. It will certainly lower the chances but a chance is always a chance.
No, It can make here pregnant with Cancer or some other desease, but of a child... almost impossible.
