we have been dating for going on four months, yes i realize this is a long amount of time. however, right of the bat we moved in together, had sex every night for around three months, didn't fight, and now, it seems that everything has changed. our sex has drasticly decreased, maybe oncae every two weeks. i've gained weight but maybe only 5 pounds. i notice myself dropping hits and smart remarks all the time, daily, about the lack of sex and how i want it, but it never seems to make a difference. the lack of sex has left me moody and grouchy lately but he doesn't seem to realize that's the reason. it's really becoming to be a problem in our relationship, i'm just wondering if there is anything i should/can do to maybe make the hint more...noticable ?
