I like to make the woman happy, and I have found that she gives more if you give more. most woman(and men) do not realize that anal is different than a pussy, and cannot be treated the same. one has to get it past the sphincter muscle to be able to have some fun, then enough lube- if one last too long ( 5-30 mins ) the anal cannot take too much pumping for normal person (not above average sex drive).
