question to the girls of reddit about blowjobs..

i was laying awake in bed just thinking about sex and all that fun stuff and i realized that ive never had a lot of blowjobs, like compared to the amount ive had sex its very very little. but i dont really have an answer to why that is. so just wondering if any of you could come to any conclusions. ive had a few partners, around 15, but 10 of these i only had sex with one or two times. i bodybuild and so i always make sure my situation is always quite clean and shit, and been told my cum tastes "much better then other guys", so that cant be a deterent. i am not circumsized but im always told by girls that this does not matter. im not crazy about blowjobs and never ask or force a girl to do one, but its always nice and never turn one down. ive gone down on a number of girls, but a number of them havent returned the favour. SO, i dont know if its because most of my sexual experiences last one or two times with a girl and girls only like to blow guys that they are with longer?, or if its because im not circumsized, or if its because i dont ask or hint for one, or if ive just run into a flock of girls who are anti blowjob. lol thanks for reading!
