I still prefer meeting guys at my local gym--in the showers and sauna/steam room. I mostly go during off-peak hours so there are less people and more privacy.
Men who sit naked in the sauna/steam room are often interested in stroking together and meeting others (Maybe a gross categorization, but I've often found it to be true). I do not mess with guys wearing shorts or bathing suits. When alone one-on-one, simply touch your dick and see if the other guys respond. Don't make it real obvious (i.e. start jerking off), but enough of a touch that lets the other guy know you are interested. Things can proceed from there.
I have met three men in this manner over the past 2 months. All older (30s and 40s), married, and looking for sex. Just like many of the people responding to comments in this forum. Each time, as soon as I touched my dick, the other guys started stroking themselves and began getting hard, which was very nice. One guy began touching his dick, as soon as I sat down. So I reciprocated, and began stroking my own dick. We ended up jerking off together.
What's nice about meeting in the sauna, is you get to physically check the guy out (does he have a nice body and dick?) The best thing is you can TALK face to face....ask each other what you are looking for (i.e. I'm new at this and want to take my time; this is my first time; no kissing; no anal, etc...) Be honest. You can also set up a time to meet, exchange numbers, if things work out... Peace.
