How can i tell if i have sperm in my penis? because, im thinking of having sex for the first time tommorow. all i want to know are the basic facts, and please give me every detail required.

Unless : Unless you've had a vasectomy or have some very unusual medical condition, you have sperm. If your partner is female, you can get her pregnant even if you don't ejaculate inside her. This is not a theoretical issue, but a very real one. Use a condom--you can buy them over the counter at just about any pharmacy (wallgreen, etc). This will keep you from becoming a father, will protect you against sexually transmitted diseases, and will make the sex last longer by reducing your direct stimulation.

Dr : Dr andrews provided you with good information. If you know this little about reproduction, i suggest that you are not really ready to start engaging in sexual intercourse. This doesn't state your age but I am guessing that you might be a teenager. There are lots of potential outcomes from having sexual intercourse to include protection from pregnancy, protection from sexually transmitted diseases, protection from your or her parents if they become aware that you have had sex and aren't happy about it. Don't you think it would be better not to have your first episode of sexual intercourse as a rush job. Take your time, learn more.
