You can also learn to squeeze perineum. You can do kegel as well as perineum alternatively.With these exercises you can develop the related muscles and can control them.
Google kegel exercises and do it regularly.
My girlfriend has the opposite problem I can help you if you can help me make it not as hot inside her
your body has an internal themometer of it's own...it will regulate itself properly. I've never heard of any drug that effects body temperature in any way whatsoever besides fever reducers of course. take a really hot bath before? if you can't produce enough lubricant, buy it...astoglide or KY....if you think your body needs to produce more, you'll have to find a gyno willing to give u something to alter your hormonal health, but they most likely won't unless you can convince them to do a bloodtest which comes back abnormal.
