So my boyfriend and I have been together for 2 and a half years. At first we were very sexually active. Then as time went on it seems as if the sex has died. We moved into our new apartment in Aug, 2014. It is close to the end of Nov. and we have only had sex like maybe 2-3 times. He says its bc he's not comfortable naked (he's a big guy) I love my boyfriend but I want sex...help?
