Are there guys out there that really willing to wait till marriage?

How many guys are out there that quickly move on to the next girl when they hear that she wants to wait till marriage? I'm 20 and I really want to wait till marriage to have . One of the biggest problems for me is finding the right guy who will also wait. I had one boyfriend who was very much willing to wait, but i really do think he was infatuated with me and maybe a lil pyscho. another guy was also willing but i thought we didn't have much of a connection so that ended. Then there were 2 other bf's who agreed with me but constantly tried to get me to go all the way. How many young guys out there do you think are willing to wait? And another guy i dated once told me that 90% of guys cheat..is this true or fiction?
