So last night my boyfriend and I got into an argue that went completely left when it came to the main topic. It started when I asked him to shave between my butt cheeks because I couldn't properly do one side. Now I have known this man for a little over 3 years I guess you could say we were friends with benefits that wanted to be with one another but couldn't get it together at the time. So we have had all kinds of sex before even a little bit of anal. So during this off topic argument he makes the comment that I have had anal sex before that he could tell by my asshole. So I'm like no shit Sherlock... I did it with you once and I had told him that I had a sexual partner back in my younger days to where thats basically all we did after super drunk nights. After he makes the comment of me having anal he proceeds to say that if some other man did it that it's only right that he does it. That I should want to talk about what another man has done to me sexually with him and I disagree with that to me it's like why would I want to know what another woman has done to my man. Shouldn't I want to figure out what he likes and doesn't like on my own. I mean isn't that the fun of sex besides it feeling good. Am I wrong for feeling that way or is this a red flag? Like I said I have known him for a little over 3 years but this dating thing is new with him. Also we are currently TTC.
