Is he pressuring me into , can he love me? please help.:( 10 points.?

okay, so my boyfriend and I really love eachother. he tells me that he loves me, and he acts like he loves me, but I can never know for certain if he loves me. no one can. I do know that I love him though, I'm so in love with him. the thing is, I'm afraid to have or go any further than making out with him, or letting him feel me up over my clothes. I can tell that it's really hard for him to stop himself from going farther, though. he always asks me why I won't let him, and he questions it all the time. but, he never tries to make me. he says that he will wait as long as I need, and that even if I can't say no (which is hard, for me) he will stop himsel for me, so I don't have to. that doesn't change the fact that he asks how far he can go constantly, and always asks what his limits are, and when he can cross the line that I've drawn for him. he's really one of the horniest guys I know, and he tells me, because we tell eachother everything. sometimes, he has to stop kissing me, to go masturbate because he can't handle the urge and the temptation. is this pressuring me, or is it simply hard for him? also...don't ask why, but I've had problems in the past, and it's really hard for me to trust guys. ever since then, I've thought that guys can either love you and not want your body, or want your body and not love you? I can't adjust to the fact that he wants both. before you say that we're young, or that we don't know what love is, I want you to know that we both take our relationship very seriously. we talk about everything..and we've bother been through what most people haven't experienced in their lifetimes. It's been difficult, for both of us. and we're not mature in some ways, (as we're only 15), but in some ways we handle things more maturely than any adult I know...so please, answer?
