I'm unclear on how condoms are supposed to be effective in preventing female-to-male contamination during "plain" sex, I mean insertion of the penis into the vagina. Let me explain.

Latex is an effective barrier to virii and germs. I get that. As far as protecting the woman is concerned, I've no trouble believing it works. The STD virii or germs are present in the semen and/or pre-cum; these are "emprisoned" by the condom, don't get out, and don't get into contact with any part of the anatomy of the woman. She's protected. The sweat of the man does not contain these virii or germs and thus no risk with the rest of the skin-to-skin contact. But in the other direction, I don't quite get it.

I searched this site after having a weird experience while masturbating, which I have now come to realize is female ejaculation. The thing is I absolutely hate the feeling that goes along with that, so I have since stopped masturbating to avoid it happening again. However I currently have a partner and we are beginning to consider becoming sexually active (we know how to protect ourselves, and are above the age of consent in our area no worries) however I was wondering if there is anything I can do to avoid female ejaculation while being stimulated by my partner. I find it to be pretty gross, though I have talked to my partner about it I am unsure as to whether or not he is ok with it. Any help you could give would be appreciated. Thank you.

How do you stay dry when having sex? I get so wet within 5 minutes.

Hi I'm a 17 year old girl and I've been sexually active with my boyfriend for a few months. We always use condoms. But recently we have been trying this new thing where I sit on him, facing him (naked obviously) and his penis is straight up and we just kinda rub up and down for a little bit. He always pees before we do stuff cause I hear that lowers pre-cum risk and also I always watch his penis as we do this so I can make sure I see nothing coming out. Also, My vagina never touches the head, it just rubs the base. Is there a pregnancy risk here? I thought it sounded safe but I still wanted to know for sure. If it's not we'll stop!
