Input: In a series of complicated events and conversations, my ex confessed to me over the phone that I wasn’t his first kiss, that he used to mess around going back and forth to his ex, and kissed other girls as well, which are things he has never told me in the 10 months that we’re together. Though he insists that he’s virgin and he just kissed other people. 

Anyway he told me that he’s clean, but out of shock (because he told me I was his first kiss and first everything), I asked which base has he been to with other girls in case I’m at risk for anything that can be transmitted through oral sex (that’s the furthest we have gone), and also because I wanted to know if our moments together were lies or real. I just didn’t want to live a lie thinking that he has never been there with anyone, since he was the first person I was physically intimate with. 

Not because that if he messed around with other people it’ll make our experience invalid or less than it was, it’s just because he lied about everything that I just had many questions and it kinda took away from how special those moments were. I also knew that there were STDs that could transmit through oral sex, so I just wanted to make sure that he’s okay so that I’m okay too. 

And immediately he got upset that I thought he’s a carrier of STDs, assured me that I was safe, and didn’t want to continue the conversation anymore. He also made it seem like it was super rare to get STDs through oral, which made me feel like he’s not really educated enough in this aspect &gt;&lt; 

AITA for asking him about his sexual history, or did he overreact to what I said? 

asking my ex about his sexual history so I can know if I am at risk for stds
