I’m 26 and have only been with men but I want to have sex with a woman.

Not just some random. We used to work together and I knew she was gay from the start. I don’t really label myself because I’m attracted to all sort of different people. I see the person on the inside regardless of sex age race etc. She left and moved to a different state but we stayed in touch.. we talked all day everyday and eventually I told her I had feelings for her and she told me she felt the same and it killed her to leave me. It’s been 5 years and we have stayed in contact. We’ve had different relationships with others but love each other. She’s coming to visit in February for the first time since she left. It’s been talked up so much that we will have sex but I have no idea what I’m doing.. I’ve never been with a woman... will it just happen? Should I look it up? Haha I feel stupid asking but I don’t know what to do.

Help me please lol
