who should I go for single or choose between the boys that I love?

should I break up with my 16 year old boy friend because my friends 16 year old brother likes me and knows who he is aand what he wants which he says is sex. I’ve only been going out with him for a few weeks and he seems nice but we are kinda far ahead for the 3 week mark we are making out in public I sit on his lap but no sex because I am a vergin and I want to loose it with my one true love. what do you think should we break up before it happens and if I do should I go out with my friends caring brother? by the way I’ve known my friends brother for 3 years and we are great friends but when I started going out with boys he was like my brother and some where in the middle of this he fell in love right when I fell for another guy. but my boyfriend is so sweetand they both can make me laugh but me and my friends brother have a connection like no other and I dont want to mess that up by going out with him or not going out with him. but I really like my boy friend me and him have had some very romantic times at the beach etc… by the way im not

please… help… by the way im 13, and if you think it im not a hore I think age is just a number and boys my age around here are so imature!!!
