im 19, single, and still live with parents. when i want to...get some release (if u know what i mean), i have to be very quiet. i have had some intense "sessions"... but i cant tell when ive come or not...i ususaly rub for about 3mins, then cant stand it anymore or my hand gets tired lol. i dont know if i have or havent though... lol weird question but i think making the noises helps u to know but i cant be vocal for obvious reasons. how can i tell if i have? i dont think i have ever quite gotten there yet though.. im not sure?
