OMG, so I have been looking through many posts that seem to relate to my issue but happycheeks you took the words right out of my mouth!
I feel the same way about my sexuality, like I don't deserve sex or just have this ethereal guilt over sharing myself that way with another which wouldn't be such a problem except I really want it, and I can't overstate that.
Sorry I am not much help, but I want to thank you for helping me. Knowing someone has such a similar concern as me is comforting.
