I want to start doing this at night with my s.o.'s help but I am sort of confused as to what I tug on and stretch. I don't pull the lips right? Do I just pull gently and tug at that bit of skin right beneath my vagina where my hymen used to be area?? I'm kind of embarassed to admit I don't know too much about the female anatomy. I didn't know what my clitoris was until i was 20.
