26 [M] first experience with another guy

First time ever posting but only 1 other person knows this ever happened so thought why not post it here.

So this first happened when i was 18 i was just out of school still a virgin etc had a couple of girlfriends but nothing serious that escalated to far etc.

Bit of a back story. Id been flirting with a girl i used to go to school with for a while and she had started i guess introducing me to a slightly kinkier side etc. after a while she said that she thought it would be really hot if i was to experiment with a guy blah blah and so on and it got me thinking.
