my own experience is having sex with gf, turn out to be so sop after long time together, so after a while just thought of cum faster. used to last 20mins to 30 bonking her but after a year 10 at most 15 mins liao..but with others, i tend to last longer, i oso dunno why, other bros got similar xperience?? perhaps my did is 'happy new tired old' (xi xin yan jiu) type!
