Quick question...

I'm seeing this girl right now, and she's amazing. One thing though, is that everytime I hold her hand, we hold eachother, or she rests her head on my shoulders, I get an erection.

Now...I don't believe in sex before marriage, and I've never had any sexual thoughts about her in any way. And when I do get an erection, I don't have any of the usual sexual urges associated with it. I just find it to be quite weird, and I feel bad everytime it happens, because I think it cheapens my strong feelings for her.

Does anyone have any input on this? Thanks for reading.
