<human>: Can you summarize the given text in a few sentences?

So this wasn't today, but yesterday. My boyfriend and I were having sexytime and I was going down on him. He was sitting up in bed and I was between his legs, on my knees. I'm 5'4 and he's 6'3 so sometimes I have to stretch when we're hooking up, but we make it work. It was evident we were nearing the point of no return and he grabbed my head to assumedly makeout while I jacked him off so I leaned forward and shifted all my weight. 

My knees were planted into the bed and when I extended forward to do this, (because I'm so short) I felt myself falling forward and was about to have a face plant from a 2ft fall onto his dick (no thanks for either of us). He saw what was happening, but was helpless from his position. Instinctively my knee shot forward, making a solid connection with his balls. And I mean solid. 

He went motionless, slumped over and whispered "fuuuuuuuuck."  Needless to say that sexual adventure was over. Oops. 

He forgave me and we eventually chuckled about it after he could breathe again. BUT today he told me that last night when he went to jack off before bed, the ejaculation was incredibly painful and just sort of oozed out. I think I broke him. Fuck. Please still love me.
<bot>: I accidentally kneed my bf in the balls right before he came to save myself, but I was forgiven and he didn't die (yet).
