I’ve been with my boyfriend for 8 months now and we’ve had pretty rough history on cheating... we both cheated on each other a lot at the beginning but hid that from each other. I found out several months later that he has been going to a gay sauna for sex. Then I confessed to him how I was still hanging out with my ex and still having sex with other guys. Essentially we got over that and decided to be exclusive 4 months ago.

I went out 3 days ago clubbing, my ex came because I asked him to come to look after me incase things got bad. I ended up drinking and taking some drugs, when we decided to go home at around 3 am, me and my ex sat in his car and started making out and I ended up having sex with him, after I felt bad that I asked to leave and go sleep in my car until I would be sober enough to drive home. I left to my car and it was really cold and uncomfortable, when I thought about going to that gay sauna to relax and warm myself.
So I ended up going there. I was still drunk so I just sat in the hot tub and suddenly these really attractive guys sat next to me and started kissing me. One guy took me to a private room and I had sex with him. Then when I got out of the room at that point I felt like I had to leave, so I walk to my locker and the other guy that was in the hot tub was flirting with me, he grabbed my hand and took me to another room where there was another guy was inside,it turned into a threesome. I ended up staying at that place for another 4 hours.

Moral of the story that things were going pretty well between me and my boy until I made the mistake of going out. I’ve had a rough time these past couple of weeks and really wanted to go out to dance and try to forget about some of the issues. Initially I didn’t want to hook up with anyone. There were a lot of guys who were flirting with me at the club, who tried to buy me drinks etc, but I turned them down.. when I got drunk, this is where a lot of the mistakes happened. I didn’t mean to cause all this, but it just happened. Things between me and my boy have been really perfect, I didn’t want to cause something that could potentially end it. The question is do I have to tell him about all this, and how?
