Cut cocks just look sexier. As far as blowjobs, I'd think being uncut would make the BJ less enjoyable on acount of all the useless extra skin. As far as good BJ technique goes, Ladies...Use suction sparingly, most of the time you want to just slide the cock in and out of your mouth making sure to give it lots of lip contact and cradle it with your tongue. jaw tension and position can make it different, but please don't let your hands do all the work. get in a good kneel and sit on your legs, then bounce kinda up and down and just angle your head to accomodate the penis as you go up and down it will go in and out, plus that will make the cock move much more which will stimulate better erections...oh and for extra pleasure, you girls must make noise, moan and groans, gasp, sigh...tell him how hard or how big his cock is or how good it feels..... ahem, sorry i'm a bj connousseir
