Premarital or not?

I am a devout 15 year old Christian who is hearing about his friends having . I believe the Chirstian Bible teaches that you should wait until marriage, and so that is what i am doing. I also do not or watch . I know no-one who thinks the same as me and am worried that i may be unable to find a partner unless I have with them before marriage. Should i hold firm and risk lonelyness or betray my religion and get a girlfriend?
