i am 22yrs old and my boyfriend is 26. we both are together from past 1year. my boyfriend is very much disinterested in sex. in the past we were active but 4months back he moved in with me and since then we had sex only thrice. i tried talking about it but he looks down at me when i express my sexual desires. I want him to want to. I'm just not satisfied anymore and i m not asking for everyday, at this point once or twice a week would be nice. I love him a lot, but not having sex has made me more frustrated. he tells everybody he is going to marry me and i am confused about what to do. is he gay? or cheating on me or impotent? how should i solve this problem
