the act of using the erect penis and flexing the hard-on while a towel is hanging from it so it looks as if the penis is lifting the towel
used by man-"before I go on a date I like to do some towel exercises"
used by women-"he can towel exercise every day but its not gonna grow his dick"
when a guy is going down on a girl and keeps licking her whole pussy everywhere,all around,including sneaking licks at the asshole and not licking the clit,resulting in the girl thinking "what the fuck is he doing down there?? that's never going to make me cum!!"
so how was he in bed? he fucks like a stallion but he had a wandering tongue....
