I'm actually very serious about this one...
First experience with another mans' cock started in the upstairs section of a secondhand bookshop- we knew each other through a mutual friend and I knew he was interested in guys like I was because the mutual friend had mentioned his interest; I hadn't mentioned my developing interest to our mutual friend but gay men usually pick up these things.
At any rate, we met in this bookshop and both ended up upstairs in a quiet section, looking at the same sci-fi books. We struck up a conversation and for some reason, we were touching each other very soon after; he had his hands in my pants and I had my hands in his pants- this was the first time I had touched a cock other than my own. I was so scared- but I
loved the feeling of his cock in my hands. We must have made out for 10 minutes before he suggested we continue at his flat.
We left the bookshop separately because I was sure that my interest in men was written all over my face, and we met up again in a park that ran along the riverbank. Hands were in pants again and he had my belt undone and cock in his mouth as soon as we had some privacy on the riverbank walk. It felt so good that I didn't think about how fast things were moving.
Somehow we eventually got to his flat and we ended up on the bed, naked and hard. He spread my legs and touched my arsehole directly; I was a little surprised at his intimate touching but managed to relax. His touch became firmer and he opened my arse with one finger, then two. My entire knowledge of MM sex was from porn and a dildo at that stage (and I didn't like the dildo much at that stage), and I was starting to feel that things were maybe going too fast when his slippery head brushed across my asshole.
Not long after he was pressing his cock into my arsehole and I became quite uncomfortable as he slipped into me; it hurt for a moment and then he started fucking me. I felt out of control, a mixture of guilt and pain but my cock thought otherwise and I came in several shots onto my chest. He eventually pulled out and came on my chest too. I recall being scared and feeling guilty at what I had done; I didn't know how people could enjoy sex like that.
I was full of guilt and worry for days afterwards; I'd had unprotected sex with a man I didn't know well enough and felt worse after going to the sexual health clinic-later that week our mutual friend showed me his clean test results, mine came back clean too. I felt so stupid but relieved too.
My second MM encounter through squirt didn't even get to the clothes-off stage before the guilt set in...
My third encounter with a customer was so different It was like night and day and we still meet up often for mutual pleasure. It wasn't until much later that I realised my guilt and fear had disappeared fairly early on with this man and I believe this allowed me to put my previous experiences in the past and enjoy sex with men.
So take it slowly...
