I was talking to a friend today and he was asking me how long it took for my previous gf to give me a blowjob. Well I asked him the same too. I got a bj after only date 2 when we came back to my pad. She didn't want to let me fuck her, I guess she didn't want me to think she was a ho. .y bud said that it took him like 2 months. .Y question is when do you ladies usually give a man you are dating a blowjob? - am pretty sure this may vary with different ages of women, but this is something I am rather curious about.
