its an interesting typic I think this myself,
thou I am a straight male myself, I find I am in the same boat and I feel more comfortable playing and just being friends with females myself.
I think part of this is because its always being the case. Because I was a drama and performance arts students. That took part in a lot of the my high schools mix choir and school productions, my class in generally have always being more girls than boys. Because the art seem to (at the time attract more girls than males to study it) so my group of the friends have always being female, and that's the same even today. I am just so comfortable around females(whether their straight, not or in-between) than males.
Even at University I lived in a house of all girls, and tbh and they were all just acted natural around me and I around them(without getting sexually gratification from my situation). Often when I get asked by guys about it and they will be like 'oh how lucky are you' and 'I bet you saw all sorts of wonderful sights' quite frankly I find that annoys me when they do that, and I often find myself 'rolling my eyes' and saying typical guys.
I guess the other side of this, is I never really being a guy, guy, sure I like the NFL(that's about the only sport I do like), but my nerdy pursuits and just how I mainly keep myself to myself or and only have a small group of friends always. I never have being comfortable around guys. I have on this site being approached by guys(via messaging or while in the chat room) and being ask if I would consider M/m or do an online rp with them. An I have tried it once or twice, but I find it really wasn't for me, and I quickly felt uncomfortable with it so I often decline now and just explain why. Some people respect that, other continue to try to get me to do it and normally find themselves quickly getting blocked.
But I would love to read other people thoughts on this thread too, I bet its interesting especially with all the other ways people identify as these days, what are the dynamics people look for these days when it comes to gender? is their a difference between how tickling is done between straight and gay people, is playing with one type of person comfortable than another, when it comes to comfort levels and such, I think its fascinating and the topic could go different ways, depending on how one perceives it.
