It's a normal thing to do, sending nudes and whatnot, but it doesn't mean it's the right thing to do. If you're gonna do it, do it safely. If they have copies of those and spread them around, what will you do? Sending images of yourself is a lot riskier than 'sexting'. Also, how old are you? It's illegal if you're under 18, so keep that in mind.
No. I don't know any female who gladly send nudes. Some girls don't mind but I never heard of anyone get enjoyment out of it.
I don't see the point in doing it with guys you have absolutely no intention of being with. If a girl was sending me those kind of pictures I'd assume she was interested in me, I don't really blame the guys really. Kind of leading them on. Imo, you should only send nudes to a boyfriend or at least someone you're actually pursuing a relationship with. Not just several random guys for no reason, too dangerous and risky for several reasons for that.
