The words of a great love guru:
'Maul her,' he said.
'What?' I said.
'Wait until she has to go to the bathroom. After about a minute, go by the entrance. When she comes out, just maul her.'

I honestly could care less what people thought, so most of the time I always had girls to hang out with/interested in me. I was always the person "most open to new things", so whenever someone wanted to do something crazy/weird, they gave me a call (and (un)fortunately it led to the propagation of a myth that I was a homo. I mean, why else would I go to gay clubs with a bunch of ladies, walk out with at least one halfway humping me, and then disappear for the night...oh wait...). Of course, I'm a REALLY effin' weird guy, so my example might not work for most of you.
My advice, though? Do it. Whatever you're thinking about (well, not anything illegal or that involves zombies -_-). Unless your relationship is VITALLY important (i.e., don't seduce your boss, not if you want a job), there's not a lot to lose and a whole lot to gain. Only thing I'm going to say, though, is think about your future as well: doing it raw may be nice, but think about if you want to deal with a kid.
...And hopefully, I don't sound too much like an All-American Douchebag.
