this is kinda fun and funny, if it caused blindness and other things i'd already be dead by now, recently its shown to increase life expectancy as i've heard. for some its not a choice, prisoners really are a perfect example of that. being that prison is one of the most poisonous environments ever though it doesn't say too much there. would "some" prefer sex on the regular, yes most probably.
this was fun to respond too haha.
