Slightly worried

Don’t let OCD rob you of the wonderful experience you had. Maybe he wanted it, maybe he didn’t. IMO as a guy, it’s a little harder to fake that sort of thing if you know what I mean.

I'm not sure how old you are, but if he didn't want to he would not have done it. He's an adult he could have said no visa versa.

I completely understand this feeling. I remember something very similar happening with my boyfriend. Where i felt super into intimacy with him and then after felt really gross and terrible like i somehow took advantage of him and forced him. He told me the same thing that he wanted to and still i felt the weight. Please remember that OCD doesn’t rest once you get reassurance. It only grows stronger with it. I understand being afraid of what you are unsure of especially when you are the type of person to worry so much about doing wrong. But someone once told me “bad people who do bad things don’t worry about being a bad person” the most pure hearted people care about hurting others and heavily weigh their actions. I feel that the compulsion of reassurance and going over every little detail in your mind will only make your mind spin more. I know it’s hard but try and calm your nervous system first and foremost and then you can work on not doing the compulsion’s and worrying about something you didn’t do. You will be okay

You can’t know his thoughts or intentions for sure. What you can do is let the discomfort of not knowing be there, and remind yourself you will cross that bridge when you get there.

We also didn’t use protection which makes me feel even worse

I have this also. This same worry
