Before sex, i would be warmed up and naturally lubricate just fine but my problem was tightening up and getting dry after one round of sex. it often led me to hurt too much to go on with another round and within the past few months things h ave totally turned around. I lubricate a lot more and now I think I'm too wet. slip n slide seems to be the motto after awhile and it is getting frustrating. Anyone know what might have caused the reversal and what causes women to lubricate?
