My husband insists that men can only physically go on with no sex (or masturbation) for a maximum of 3 days. Is this true?

not true. i think depende xa sa tao, sa lifestyle esp. if working and bz un guy d n nla priority un sex, and baka sa age na dn cgro if younger pa un guy mataas pa ang need nun for sex pero un sakin kc 37 y/o na xa. since pregy ako ayaw nya mag-do kc natatakot xa madaganan daw c baby hehe.. 7mos nako now cgro mga 3x ko lang xa napilit cmula nun nbuntis ako haha. pero baka sariling sikap xa most of the time not sure.. more on game xa sa fon nya after ng work so rem time nlang nya is to sleep.
