The first man that ever fucked me was a stranger at Flex when I was 18, this was probably my second time there and the majority of my sexual experience was mutual body contact with my brother (I am a year younger but arguably shared him almost everything I knew from jerking off to discovering porn on Google...lol but that's a story for another thread.) I was in the steamroom and one guy was there, and I was walking out when I heard "Nice ass." I of course turned around and sheepishly said "Um, hehe...thank you" which led to asking if I'd ever been fucked to which I admitted a guy had tried but didn't succeed as it was painful.
"i'll be really gentle" was his reply and how could I say no to that? I was very shy at the time and unable to turn down most men who made an effort to compliment me for a couple years at least. I remember getting on all fours, with my towel underneath and true to his word I don't remember it being painful at all, but I don't recall much of the actual fucking either except it was not more than 5 minutes or so.
"I won't cum in you" was what he said and I said "Okay" but I had no idea why he said that because I was ignorant to STD's and HIV and associated risks. He slid in me without a condom, by the way, which I figure now was what I would then associate with pleasurable sex (I topped bareback my first time that same or the next visit, which is also a story for another time.)
After a few minutes he slowed down and stopped, and said "I gotta renew my room," which I later (and usefully) learned is the old standby for escaping a situation at a bathhouse and left me waiting, still on my fours, for him to come back. After a few minutes I was wondering where he went and instinctively reached around and felt/smelled the soon to be addictive feeling of cum in/on my my hole... and I remember feeling dirty and used, but certainly not turned off and I credit that moment with starting my journey as a raw cumdump.
Anyway, the point is that I don't remember what he looked like, nor his name if we had even exchanged those, and that I enjoyed the experience although it would have been hot to tell him how I evolved from that point on.
Phew, I have never written that down, at least not so detailed for sure and I have to say it feels cathartic to recount and share with a community who is built on the appreciation of bareback sex!
