Welcome. The more recently the separation from religion, the more likely you are to feel anxious about it. It gets better. Personally when I realized I was an atheist it was like a load off my shoulders, but YMMV.
I was a late bloomer when it comes to sex, my denomination (United Pentecostal Church) was very repressive sexually (select only a date who would make a good mate!). What we did was more like courting than dating, and sex before marriage was prohibited (and they took it about as seriously as most Muslims I've met). It took awhile to get over, but I'm much better now. Don't expect your sex life to change over night, if you took your denominations sexual prohibitions seriously.
It might help you to talk to a therapist if you want to adjust more quickly.

I'm not anti-Christian. I'm anti-stupid.
