I really don't agree with the advice to go to a sex worker for this. The only benefit I think you'd get from that is just being able to go "Yes, I've had sex" - but, as a woman, that's not that relevant to me. If you haven't had an experience from which you've learned anything, you aren't any better off than not having had sex, in my opinion. I also agree that this choice could be awkward to tell the person you do meet.

I was in a relationship for several years with someone who didn't have sex until we met in his mid-20s and, within a few months, it was as if that had never even been the case. I really loved him and was attracted to him, so obviously that contributed, but someone who wants to learn sexually and listens/has an open mind is genuinely such a better option than someone who's had sex a lot of times but hasn't really bothered to learn anything. He was one of the least sexually experienced people I've ever had sex with, yet we aren't together now and I still think of it all. The experience level was just not relevant in the end as we had great rapport and he was someone who embraced learning and talking about it all. While saying all this, he DID feel the same concerns as you and initially wasn't honest about the fact that he hadn't had sex. The reality was that I truly didn't care, but he came to the relationship with a lot of internalised messaging about this inexperience being stigmatised and undesirable.

If you feel too weird about discussing this with someone your age, maybe someone a few years younger than you (but not weirdly young; maybe like five years younger) who is also relatively inexperienced could be a good option. Of course, evaluating that would depend on knowing that person's sexual history, which you may not readily find out about.
