Romantic gift ideas?

I’ve been with my boyfriend for about 3 months and a half and we’ve been a lot together, like my parents dissapproving about me having a boyfriend because they say im too young [15] and his not a christian xD, and loads of drama was going on and stuff, we havent seen each other through out the summer hols and those are one of them…

and through all of that, even the little things and simpliest things he do just to show me that he loves me no matter what, just made myself think about how he has been there by my side all of those times, and that for the first time ever; I can see myself being with him forever and I found it hard to even imagine it before because my ex boyfriend messed my head up and I got scared to think about the future with anyone and my boyfriend has always talked about the future :] and now I truly love him and can talk about it with him =] and I just wanted to know any good cute romantic gift ideas just to show my boyfriend I really love him, and were 15 so nothing like older couples do :S [like sex] I don’t give myself that easily im those type of people who believes in sex after marriage lol… anyway thnx ♥
