My boyfriend says he feels guilt tripped to have sex

I admit, I have a high sex drive and no one has ever kept up. But when I met my boyfriend he is the first person to nearly out sex me, he just kept going and going! It blew my mind, no one has ever made me orgasm before which is probably why I keep going. More recently I have been dressing up in lingerie to surprise him when he comes home but he has started to push off sexual advances, and purposefully ignore me when he knows I'm horney.. last night he told me that when I plan things like that he feels forced into have img sex, because if we don't I'll get upset. I sort of walked around in my lingerie for three hours before awkwardly taking it off in bed. I don't know how to stop him feeling this way, when all I want to do is get intimate.
