I know most guys just want girls for sex until they're older, but...?

if I'm in high school, and I have a boyfriend who hasn't forced anything upon me, could have so many times because of my submissive nature, truly seems concerned about my overall well being, and doesn't want to give me his HPV, do you think he may actually care for me? Or... is it probably just other things? I DID tell him I'd get the gardasil vaccine... I'm 15 and he is 17... but, coming from guys, I want an honest answer. I can take it. Does he probably really like me? Or is it just hormones/sexual attraction? :\
