Hello all. This is my first post. I have been following this forum for 3-4 years and finally decided to join. I really like the community here, found many topics and replies helpful, but never had real need to join until now. Btw I'm 24 years old guy. I'm in relationship for 9 years with one girl. This is the first "real" relationship to both of us and first (and only) sexual experience (I guess ). Endowment - little more that 7" with average thickness, curved down (not much). Now the problem... A week ago I began to feel pain while urinating, also some kind of yellow secret in my underwear. Besides this, sperm color sometimes changes to yellow-green and the amount of it is much lesser than usual. Yesterday went to see doctor and found out that I got sexually transmitted disease (she didn't tell me what exactly, we are waiting for lab results). She told me that it is nothing to worry about, however I should be aware where and from whom did I got it (funny line, really). I think you can see where's the problem... First off all, my gf is my only sexual partner. Also, in last month we weren't that much sexually active, 4 times top. I asked my gf, but she says she doesn't have any symptoms, except she got her menstruation 6 days before she should (don't know can it be related?). How is this possible? The only other possibility is that I got infected by friend's diving suit which I wore 10 days ago. I asked my doctor about it, she only said there is always possibility. Further more, we had much less sex than usual. In general, I was the cause because of exams and my part time job + unbelievably high temperatures. She mentioned me, in a funny way, that she will find another guy and I understood this as joke, of course. Then last 2-3 times, she started to complain how the position doesn't suit her because of my curved penis. Those were standard position we mostly have and she never complained before. I don't want to rush with conclusions, but I would like to here other people opinion. What is the possibility she has another guy (or I'm just paranoid?) or I'm so unlucky to pick up infection from my friend's diving suit? Sorry for the long post, also English is not my primary language, quite obviously. Thank you.
