Re: lol
I don't get that.
Unequivocaly...going down on her.
Why?
You're not protected unless you have dental dam, or suran wrap.
Her fluids, and any diseases, go right to your mouth and into your body.
At least with a condom, you're not in direct contact, so you have a chance of avoiding most stds. Obviously, some regions of you, will touch her, so anything just outside her vag will likely be given to you, like herpes or hpv/warts.
Never go down on a random hookup. Never.
