Playing guitar has got me into at least one girl's pants. And it's certainly assisted with at least two more.
Amusingly my ex-wife is probably the one who gave the least shits about it.
I'm reminded of my ex who owned a guitar and he'd hold it on Skype sometimes but now that I think about it, I don't think he ever played it. I even remember calling him on Skype, it took him a few minutes to answer (when he'd normally answer instantly) and he was sitting on his bed, turned away, posing with guitar, strummed for a few seconds and then turned to the camera all, "Oh, hi, didn't realise you were there!"
More guitar: My brother tried to teach me bass when I was in my early teens but we both gave up after a couple months. He still plays but I think we were still in the hating each other stage of our relationship and it was a bonding experiment that didn't fully work.
Not guitar: My partner likes games shows. A lot.
