I really enjoy with DermalMD Vaginal Tightening Serum. I apply it with my middle finger at first then try to apply with a tampon which worked better. It tightened me & almost INSTANTLY increased my sex drive to a 10 lol. Did not dry me out actually did the opposite for me. My boyfriend preformed oral sex & there was no taste or smell. I also used it three days in a row with no side effects. The effect did not last long though maybe 40 minutes
