Im 18 years old I'm young but in a serious relationship with my boyfriend the problems is that I felt like bumps down there and I'm worry if its like a virus... my boyfriend is the first guy I been with and sometime we don't use condoms I'm scare :( those any body know about this what should I do?

Even if he is the only one you have been with if he has had past relationships he could have gotten something along the way and passed it on to you
It could be genital warts you need to get it diagnosed by the doctor though.

Are you planning on having a child? if not than why not use a condom every time?
