Ok, I have posted on here a few times so if I repeat anything that I wrote before I apologize. I am very worried about doing any kind of sexual things. Its to the point I worry about kissing. My boyfriend and I broke up about 4 months ago and I started dating another guy, all we did was he gave me oral and I gave him oral for a few seconds and just mutual masterbation between each other, and him fingering me, but he never touched me and I never touched him after we touched each other..I usually made him wash his hands if he went to touch me after touching himself. Well I was having what seemed to be a yeast infection and had it for a couple of months. I tried using monistat and it didnt work so I went to get tested for things and they said it was trichomonaisis. Well I was not sure how this could be trich because the only person I had had sex with for the past 4 years was my boyfriend. And the guy I was dating after that we never did much for me to get trich. Well I took the medicine and it cleared up, and then the guy I was dating gave me oral sex again and the next day it seemed like it was itching around my vagina again. I am not sure if I am just jumping to conclusions or over worrying or if it is from shaving, Im not sure. But could this just be me being very sensitive down there? I also asked my ex boyfriend and this guy about things and my ex hadnt been with anyone else and this guy said he went and got tested and things came back ok. So Im just not sure how I got this or why I get so irritated down there. Its to the point that I freak out and dont want to ever date anyone again. If a man gets tested for trich will it show up? Or is there not a way to test a man for trich? Also should I be extremely worried about getting other stds from doing what I did? I got tested for hiv, gonorrhea, and chlamydia and they came back ok. I am planning on going back to get tested for hiv again in a few months to make sure. But I am worried now that after I got tested for all of these things and they came back fine and then after that I wetn and messed around again with the guy I was dating, I am afraid he went and dated someone else in between the time we dated and now. It was maybe a few weeks. (if that was confusing to anyone, the guy after my boyfriend we stopped dating because I freaked out so much about stuff like this, so it was maybe two weeks when we stopped and then messed around again) So now its kind of like I have to worry all over again. If anyone has any advice on any of this I would appreciate it. I just analyze everything and worry so much I dont know if I have to be worried or if I just go over the top. Thanks.
