If you want to shave and she wants you to shave....DO IT!
I know a lot of people on here say a man should be natural. Well, here's a story for that. I'm 47 years old, a bit overweight, balding, just average cock, always been very hairy all over, nothing really special about me. 2 months ago my now x-gf, talked me into cutting my remaining hair short as possible without shaving my head, then she took the shavers and removed ALL THE REMAINING BODY HAIR, then I shaved with a razor.
I felt great, cooler in the hot weather and have had more women come onto me in that 2 months than I have in a long time. I had 2 women that thought it was odd, but, they are friends and were used to what I looked like.
Maybe it's were we live, maybe it's something in the water (LOL). I don't know but for some reason, it's working for me. For some odd reason, it makes me feel a bit more confident (maybe it's that "visual inch" thing) I don't know, but, it's working so far.
Give it a shot. If you don't like it, so what, it will grow back.
