for about a month or so my boyfriend and i both have been a little worried and yes we have sex. last month i was very itchy in my genitals and if i itched it, it would burn-- that just stopped happening. one thing hasn't changed though; i get this really strange pain like up in my vagina, maybe near my cervix? and i have no idea how to explain this pain, and it's kind of not like a real pain but i feel so weird and i feel really weak and out of energy when i get it. i also just had like some sort of boil/pimple near my genitals, not on...near them, kind of still onmy upper leg my very close to them. it wa sreally big and you could tell it was filled with blood just by looking at it. i popped it and only blood with a little bit of clear puss came out. i'm scared i could have cancer or and std. can someone please help?
