Im a 21/male....and i notice ever since i first first started fooling around with women at the age of 14 till present I find that when ever im kissing or just giving them a massage, my muscles go into spasms. Not to the point of having a seizure, but my hands and legs shake uncontrolably. I could be calm as ever and not be nervous, but they still go into spasms and i have no control over it. Anyone else experience this. This only happens with new women i fool around with for the first time.
