I'm 14, have a bf, should I be sexually active if we both want to?

Im wondering, i am really inlove with my boyfriend, and he says he feels the same, we write to eachother paragraphs about how much we like eachother and we made sometimes dirty jokes to eachother and stuff, like shutup or you can suck my dick, and I think to myself, because i love him so much, i wouldnt mind doing it and stuff, but I feel like at 14 i will regret it, but he's the first boyfriend i ever fallen inlove with, my other ones didnt  work out... I really love him and i hope i can take it to the next level, but im too scared everyone will call me a slag? If i love him this much, i mean maybe i can..
