They’re a secondary sexual characteristic, so it seems like something that would get attention.
I used to play Counter Strike a lot, and I generally played with randoms. It feels weird (but in a nice way) the number of people who have told me how nice or attractive my voice is. Admittedly it was mostly guys, and I’m straight, but it’s still a good compliment to get. I did make a lot of female friends on there though, with me consistently playing with one group. I don’t know if this is because of my voice or because I just treated them normally, but the voice didn’t hurt.
… I don’t really know why I wrote this. I guess just as a general agreement women like rumbly voices, which I don’t think was needed. Oh well.
