I’m 42 straight/curious. Questions about anal..

So I’m recently divorced, never had no urge for a guy on guy thing. However i did a spur of the moment thing and booked a cruise over New Years. While on the ship late one night a guy randomly offered to give me head. (I don’t think this was random, I purely believe now this was a cuck situation as early that evening i met a lady who was very aggressive in wanting sex. I never seen either of them after that night for another hookup but i did see them together throughout the remainder of the cruise).

Back on topic i apologize. Anyhow he asked if i had ever tried it models which i have not and told me how good it was. So I’ve been opening up and scrolling and now that I’m more into trying this lifestyle I’m seeing guys having sex. I’m curious how that is. Do you need to prep for it? Are other guys into hairy men? And can i really cum from getting anal? Tia and excuse my ignorance
