I remember meeting one partner once at the local pool.
I used to go swimming several times a week at the same time and naturally you tend to bump into the same people who have a routine.
There is this one older mature gentleman that would often say hello and chat a little bit to me both before and after my swim. Over the course of several weeks we develop a friendship and discussed swimming. Occasionally he would comment on a few women that he noticed swimming and I just totally assumed based off that he was straight, looking back I guess he was testing my sexuality. Up to this point there was no indication to me that he was gay or bi with anything he said or the way he looked at me. Mind you I was younger and very inexperienced. If there was signs, I wouldnt have known.
One day after a few weeks, he sat next to me in the spa. I noticed and felt his leg rest/touch my leg. I was very flattered that he felt that comfortable and at the same time didnt make anything of it as I just thought he was manspreading and it as more accidental contact than deliberate. Not to mention there was other people in the spa with us, so we were not alone.
The next time we sat in the spa together it was just the two of us on this occasion and everytime he wanted to ask me a question he placed his hand on my thigh to get my attention, until he finally just rested it there. Of course I loved it and got extremely turned on, as this was the most public I have ever been with another guy, but being naive I just continued to talk to him. I still thought that was just the manner in which he communicated and he was just being friends with me.
He then slowly moved his hand over and rested it on my erect throbbing dick. At this point I was only more nervous about being caught then anything else. I guess it was only now that I realised that we were not "just" friends.
I was careful to not make him feel that his advances was not welcomed as I didnt want to scare him away. So I told him what he was doing felt really good, but was feeling hungry for lunch and suggested we could go back to his place. We both showered at seperate sides of the male shower rooms and I just met up with him at his car. On the short drive back to his place, we chatted normally and when we got to his home, he actually served me lunch to my surprise as I thought we would immediately be into it when we got there. I think he was just making sure I was totally comfortable and not scare me off.
After lunch we sat on his couch watching TV for a while, before he made his first move. He layed me down on his couch and started passionately kissing me, while undressing me and the rest is history. It remains as the longest foreplay I have ever had with a guy where it took several weeks for us to go from "just friends" to sex.
