Guilt/Shame

I’m 23 years old and still a virgin and have had some sexual experience but it’s very limited. I feel when I do I have slight shame/guilt afterwards questioning if I’m moving too fast (although for the other person it’s probably slow). For example, I’ve started dating recently and I had a third date with this guy and I was enjoying myself so was just going with the flow of things. I am open to having more experiences I especially since I feel I am very patient and selective to who I share myself with but don’t understand why I can’t allow myself to enjoy these things after. Could it be because of past trauma? I want to be able to enjoy myself without feeling these things or feeling my partner is thinking negatively about how “fast” I’m moving. (P.s. if any one in the comments could give me extra advice in addition to your comment let me know please and I’ll message you :)).
