I agree with Sara. If you don't wanna, don't do it.
But let me point something out...you have mostly guy friends but you have problems with some nudity and vulgarity, or are you just like that online? I don't know about any other guys, but when I'm trying to get somewhere with a girl, I'm gonna be classy. If I want to hang out and have fun, I'm going to be myself-- which can get pretty vulgar. But that's just me being a dude. So if I was really friends with a girl, like she was "one of the guys" I'd treat her accordingly.
