Boyfriend has lost his mojo...any tips?

Title says it all really....

I’m 22 and my boyfriend is 31, we used to have crazy spontaneous sex all the time but all of a sudden he’s not ‘up’ for it.

I don’t want to go buy toys, undies or anything like that. I just want to know is there anything I can do to get him more in the mood without it being too much for him?

I don’t want to pressure or force him in to having sex with me.

I tried giving him a nice massage the other night while I was in my undies but he felt too sleepy after 😂😂
