45 [M4F] looking for young, nerdy / geeky women to chat with

Ok, this is my first time posting here, so I hope I wouldn't break any rule, lol.

I am 45 cis male, nerd and a geek who loves video games, board games, comics, science fiction, fantasy, roleplaying games, heavy metalz hard rock etc... I am in an open relationship (my partner has a secondary partner), and I am looking to get to know someone new to have sexy chats with.

I am into light BDSM as a dom. nothing too crazy, mostly bites, hairpulls, spanking, and some light choking/ gagging.

You must be able to hold a decent conversation about non-sexy stuff before I am able to open up to more serious flirting and sexy talk, so if you want something more short-term I might not be the person for you.

Age wise, I prefer women around 18-35. There is nothing wrong with older, but generally, I find that I have easier time chatting with younger women.

So, umm, yeah. I think that's about it. If you think I should add some extra information please let me know.
