If found out that your voice, used correctly, can be a factor in getting laid.
If I like a girl, I will get her number and call her. I found out at my work that a lot of women like my voice, they think it's horny.
So I call and talk but let the conversation be about sex... Sometimes it makes them hot.
At some point I will ask if she has ever done phone sex before. After some talk, and letting my voice get hornier and hornier, I will ask if she wants to play. I slowly start to temper my voice and start sex stories about how I want to do it with her, where, when etc. And not no porn stuff but like I want to touch you here and stroke you there, like at your clitt and slurp up her hornyness. After we both have played with ourself and come real great (I will let her hear I enjoying it) they usually are interested if you can make your little story come trough.
I'm not no handsome mofo, but my voice has done great for me. I was always chicken to talk to a girl that I didn't know but on the phone, it's quite easy for me to get what I want.
