I think I messed up really bad...

 I'm sorry if this is tmi.
DH and I haven't been having sex very often. Well tonight he finally initiated sex, but he got off really fast. So I thought hey let's try someone exciting and use a toy. So I asked him if he would want take care of me with a toy and he was kind of hesitant but decided he'd try. Well, afterwards he was really hurt that I seemed to really enjoy it. Saying now he feels inadequate like he could never make me feel that way. I tried to explain that it's a totally different experience when it's him and when it's a toy and that I'd choose him over a toy any day. Well he said that he understands what I'm saying, but he knows what he saw and heard. 
So now I feel so terrible, and that I royaly screwed up our already strained sex life. I hate myself for hurting him when I was really just trying to try something new. Idk what to do.
