I'd second what Poppinjay said about doing tech for a college play. It's not too difficult to figure out lighting, sound, etc. - especially for someone with a technical mind - and just hanging out with the drama folk can be very entertaining - and "revealing"
It'll be a bit awkward at first, going into something completely new, but as you get the hang of it and become more comfortable - you'll start to open up and there will be plenty of women around, so it's a generally good environment.
