I think I made a mistake 😬

So I went out with a male coworker that invited me out to drinks. Long story short… on the drive home, he told me he thought I was cute and is interested in me. He kissed me and we basically started making out for a good while. He grabbed at my breast and kissed it.

I liked the kissing and attention and everything but I don’t like him in that way. However, I ended up giving him a blowjob that I now think might’ve been a mistake on my part. Idk he’s really nice and I’m not particularly attracted to him but he’s not ugly. I don’t think I could date a coworker tho.

Idk I feel like I shouldn’t have given him head, but at the same time I wanted to experience doing that to another guy since I’m 25 and only had one bf before. I guess I just did it for fun and now feel guilty about it. 😣lmk what your thoughts are on this and what, if anything, I should do to remediate the situation or how to explain to him what I’m thinking… :/
