Waiting or na

My boyfriend and i have been together for over six months now and haven't had sex. He is my first boyfriend but has had past sexual  elationships before. We've been waiting coz I'm not ready yet but I'm starting to get to the point where I might be soon but I still don't know if I would want to just yet. I love the idea of waiting till marriage for the fact that you lose your virginity to the one person you'll be with forever but I'm not as keen on waiting such a long time. I love my boyfriend more than anything and plan to be with him for life but I know shit can happen to the best of relationships so im scared to do it and  reak up down the track. I want him to be my one and only. Any one with similar situations or opinions on waiting till marraige❔
