I'm dry before my boyfriend and I are about to have sex. What can I do to fix this problem?

I have a questionable ailment...I've developed a rash the day after my boyfriend and I have had sex but we've been together for 3 years, lost our virginity together and stay monogamous. So I can't see any risk in any STIs although I am planing to get a check-up soon. The rash is around my vaginal area but also near my bottom. I'm guessing I'm allergic to the latex or lube used or it could be because I shaved...should I be worried? Thank You

Every once in a while I will have a problem staying wet when I'm having sex with my boyfriend. I'll start out wet, but then will dry up and we will have to stop because the condom will break or it becomes painful for him? Is this normal? What can I do? Please help, I love him so much and I definitely love having sex with him, but I don't know what's going on? Thanks!

I'm quite allergic to latex. I've never had sex before but me and my boyfriend are thinking of having sex. I'm 15 and he's 16. He's not a virgin. He knows that I'm allergic to latex, too. When I'm around basically anything with latex in it (like balloons, latex gloves.) my eyes get red and itchy and my throat itches, too. I don't think it would be a good idea to use a latex condom but would there possibly be any way without having an allergic reaction to it? I don't want to have an STD either and I heard lambskin condoms don't protect against STDs and they rip easier so I'm really worried on what I can do. Would it be o.k for me to just go on birth control? What should I do?
