Ill be honest,I can either be really good or suck,for me its all about the girl,she has to make be want it so fucking bad that Ill lick until my tongue goes numb and fuck until I get light headed,otherwise Ill have a 5 minute fuck,nut and goto sleep.
with my one ex we could go for over a hour because she made me want it so bad,but Ive been with other girls who only say the 5 minute me because they werent into foreplay or whatever.
but beside that factor I can tell by body language what a girl like and then Ill do that,I think alot of guys have no idea how to read these signs and they do what makes them feel good.
