Hey Fawn, pretty exciting stuff being in love.
I haven't read everything written above but would like to put in my 2 cents worth.
1. Get over the idea that what you've experienced sexually doesn't change your sexual identity. A very important part (not all) of who we are is molded by what we do, who we know, and all that. There is no RESTORE button on life.
The issue here, it seems to me, is whether you and/or your lover feel that the imprint and effect of your sexual experiences is something that needs to be forgotten or forgiven at all. I question whether they do and if it's a big issue to either of you I'd suggest that rather than drifting off into what you hope will be a sweet future, you pause (there is a PAUSE button!

) and get behind the inner assumptions that lie behind that. Did that make sense?
What I'm trying to say is that if your man considers you tainted in any way by what you've experienced, I'd go slow with him.
2. It seems to me that the issue going forward is this: What role will fidelity play in your relationship?
Someone above mentioned the "underlying causes" of a woman choosing sex-work, or even considering it as a possibility. It's worth spending some time on that because it might have real impact on the "success" of your relationship. And the same goes for your man if he is/was a hobbyist -- it WASN'T just because mamma wasn't giving him what he needed, and the impulses that led him to first consider and then follow thru on engaging the services of prostitutes aren't going to vanish simply because he has a willing and skillful lover at home. Does that make sense?
So, anyway, whether you agree that sexual fidelity is or isn't going to be a big issue, you both have to be able to reasonably expect that you can pull it off or you're setting yourself up for a bad time.
You're amazing Fawn. Good luck.
