Alright, believe it or not i've actaully had a similar discussion with my husband, this may not be YOUR particular problem but I'll tell ya what OUR problem is:
You fuckers don't give us any feedback!!!
You don't groan, you don't moan you won't say "YEAH!!! Oh that feels GREAT!"
Feedback is NOT thrusting your hips, you do that no matter WHAT touches your pecker! I need an UMMMM HMMMM or an OOOOOOOOO.
WTF do you think women are so vocal??? We know you're not fucking mindreaders! If you're messing about south of the equator and you get a nice throaty groan do you move onto something else??? NO, you fuckin stay there and keep working it, you know you're onto something good.
So if you're getting inferior quality blowjobs think back on how much information you're giving your partner.
