Group or supervised Date legal, any physical contact of a sexual nature, felony that gets you jail and having to register as a sexual offender for the rest of your life! Yes, even a mouth to mouth kiss!
I never had a boyfriend with the same age. So I guess that's pretty alright? I think it depends on the couple. I'm 14 and I'm dating a 19 yr old guy. My dad knows but my mom don't. My dad said that it's fine not unless we're trying to do something that inappropriate. You know that stuffs right? My boyfriend respect me on whatever decision I make and that's cool. It really depends on you two.
I'd say no. I don't think it matters for just a three year difference, because it really doesn't matter at all when you get older how many years younger you are then him or even the other way around. All that matters is that it's legal and parent/guardian approved.
