Im about to do something with a guy for the firet time [MM]

Been a very long time Lurker, can’t really remember how many times i came to stories in here.

As the title says, tonight might be the first time i have a sexual encounter with a guy.
Been straight my whole life but for the past few years i started looking a lot more at feminine guys. Well i found one on Tinder and he might come over tonight. If you have any tips it would help lol
