i dont consider myself a heavy sleeper but Sex does KO u completly, my ex is a nympho' she f**ked me while i was asleep once and i thought i was dreaming i nutted and everything, idk how seeing as we f**ked for 6 hour's before that.
Women just cant say no -___-,
but as far as sleeping w/o alcohol or drug's goes i just wake up with certain noises, loud music (ear bleeding), shot's, screeching, people yelling i can sleep thru that; but bird's and my own family talking idk i just cant.
i guess your a product of what's around u and u get used to it.
