Don’t know what to do!!

So basically me and my long distance boyfriend officially moved in together in November and at the start I thought “this is finally it I can get sexy reasonable amount” and at the start it was so good and regular but now he’s either “too tired” or “can’t be

bothered” which does absolutely nothing for a girls confidence!! And we’ve talked about this and he said “it’s nothing to do with you it’s just sometimes I don’t want to” but I feel embarrassed cause I have an extremely high sex drive and when I try it on he shuts me down and I dont know why I can do!! Girls some advice pls x
