<human>: My boyfriend [M18] and I [F18] have been dating for about 7 months now. Early in the relationship he told me that he has some varied interests in the bedroom, cross-dressing being among them. 

At the time, it was just a theoretical interest, nothing he had pursued. I'm totally fine with him exploring in private. In fact, I've even participated in small amounts by teaching him about female clothing sizing and things like that. 

However, he has recently been exploring in small ways like wearing panties instead of boxers and learning to apply a small amount of makeup. The thought occurred to me that he may not be entirely straight. 

We've talked about it and he says that he doesn't know. We are both young, so that's understandable, I'm just starting to wonder what the implications for the relationship are going to be. We've been playfully planning a future together (I know it's early, but I really love this boy), but I can't help but to think about what would happen if he decided years from now that a traditional relationship isn't what he wants. 

Is this an early sign that he may need something else out of a relationship some day, or should I just love him and hope for the best?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My boyfriend has started cross-dressing. Is this innocent exploration or could this be a sign that a traditional relationship may not be what he wants in the future?
