I'm 17 and a virgin. But I've tried to have sex with two different people but I can't because I am too tight. I know you're meant to be tight for the first time but whenever I try it's a really un-bearable pain and it makes me feel sick? I've tried everything like lubricant and things like that but it doesn't work. Above the opening of the vagina is a lump, its been there a while but recently (like the past few weeks) its getting bigger? And when I touch it, it make me want to throw up? I'm too embarrassed to go to a doctor though, what could it be?

If you are too embarrassed to go to a doctor, you are too young for sex. Why? Because once you begin to have sex you have to see a doctor yearly for a female exam and a PAP smear. Also, it would be wise to be using birth control if you are having sex. Unless you are using a condom or spermicide (both have a rather high failure rate), you have to see a doctor.

Lump that is getting bigger, and hurts and makes you feel sick. I would be rushing to the doctor.

So find a women doctor to go to, You need to get over embarrassment, and not sure embarrassed over what ? Seeing a doctor about a medical issue, As a women you are to do self exams and see the doctor if something is wrong.
