...Massage "tingling"? I have used it for a while for multiple reasons with girlfriend etc and I have noticed a red spot on bottom of my shaft and i know it shouldnt be a reaction with my gf because be and her have been doing stuff you a year and i have not had any problems and she has been tested...one of the other things that lead me to believe it could be the lube is that it happened on a night i left it on til the morning so if anyone has a answer... let me know thanks!
