my boyfriend lives in my neighborhood .

so I'm almost 15 and he's 16. so everyone in my neighborhood is really close . all the kids , & we have lots of cookouts & go swimming all the time. My boyfriend lives right in front of me on the right side . so we're really close . his name is Justin . anyways we met and we always kinda saw each other here & there but never spoke, like at the pool or him driving home from school and i would be walking home. he said he always wanted to talk to me. but we never did. we been dating for a couple of weeks . even tho we live in the same neighborhood he knows that i still have a strict boundary of not doing sexual things with each other. and he knows that . I'm a virgin & he is not . I'm basically just saying that I dont want one day for things to lead to one another if I allow him to come over. I'm just excited over all these new feelings . how do I keep these boundaries established . I dont want to do anything stupid one day
