No, for a person to get HIV they have to be in contact with a person that has HIV. sperm will not create HIV no mater where you leave it or what you do with it.
The chances is great. It does not matter if you sperm or not you should always wear protection.
Low
You most certainly can, sperm count has nothing to do with it.
Circumcision has nothing to do with catching diseases
No.
A woman is just as likely to get HIV from a military man as she is to get it from someone who is not in the armed forces.
Women do not have sperm. If you're talking about a woman's vaginal secretions then yes it is possible and does on occasional occur during unprotected intercourse.
HIV/AIDs is spread through contact of mucus membranes like the mouth and genitals. The prostate is an internal organ.
You can, even though the chances are reduced.
If the man truly has a zero sperm count then the chance of the man impregnating someone is zero. However men with low sperm count can impregnate women and men with high sperm count may be unable to.
Girl sperm swim faster than boy sperm. If the man ejaculated when he wasn't very far inside of you, chances are you'd have a girl. The hormones/birth control pills wouldn't have any affect on the sex of the baby because the man's sperm determines the sex.
No, circumcision does NOT prevent the transmission of HIV. Condoms can dramatically reduce the chance of HIV transmission. There's some evidence that circumcised men face a little less risk of catching HIV, but that's still far away from saying it's safe.
No. HIV is spread through needles, anal sex, and many other things. Sucking a man penis will not get you HIV.
Only with possibly catching an STD. Other than that, it's just protein and water. Nothing to get excited about.
