I'm a guy and I haven't been with another guy but I want to try. Nervous as hell...

Hey everyone. So the title probably says it all. I've been interested in trying to have a woman bang me with a strap on but haven't had much luck in finding a woman who wants to. I am ready to try being with a guy but really nervous about it. Hoping to find someone to take it slow. I'd appreciate any advice anyone has. So far I've heard the following from other sources- Use an enema before hand, bear down when the guy is going in. I'm especially interested to know how people have met up before. Craigslist? Grindr? Local club?
