My boyfriend is now the first guy to actually make me orgasm!!! OMG! YAY!!!
I guess it's because he listens to me, and does what I ask him to do, and now he knows what I like. =]
I love him, and I think that fact contributes to it too. I mean, in bed, when he's horny, I want to please him, and make him satisfied, and I know he'd do the same for me, so I get horny too, so I enjoy what I'm doing to him more, and I know he enjoys doing stuff for me too, so I get really horny, and come closer to climax easier.

It's now the same with fantasies too. If I imagine it's my boyfriend in the fantasy below, I climax so much quicker than if it's a stranger.

I know that might seem weird, because the people in the fantasy end up killing me, but obviously I wouldn't ACTUALLY want that to happen, I'd want someone to ACT like they were going to do that, but if I said a word, they would stop at any time. So I reckon that's why I'd come closer to climax quicker if it was my boyfriend, rather than someone else, because I trust he'd stop if I wasn't enjoying it. =]
