I've had plenty casual no strings attached encounters with girls over the years, but every single one has involved at least some dialogue, some kissing and a little closeness. However, my experiences with men have been very different, although I should say that apart from one, they've taken place in the sauna. The last time I visited, I was sitting in the cinema room when a guy walked up with a hard on, removed my towel and wanked himself onto me while looking at my cock. Not a word spoken! I didn't mind of course, he seemed to enjoy it, and I must admit I enjoyed watching him coming as well, but I thought some sort of introduction, even the most brief, was the norm? You can't get much more casual than that.
