first time

So im 15 and im thinking about having my first time but i dont know if i should. Like im scared if i tell my freidns they r gonna be like what? why? and already? My one friends mackenzie shes already done but my other friend susana hasnt done and only has given blow jobs. I just dont know what to do. Like i dont really care about how ur first time has to be romantic and u have to be in love.
