Girls 18+, would it be a turnoff if a guy wanted to wait until marriage for ?

I am strongly considering it for religious reasons. It just seems like it would be hard to find a girl that wants to wait that long. The next best thing would be waiting until in a committed relationship. Honestly me personally I'd be ok with the latter option but I feel it would be best for my relationship with God to wait until marriage. The girl doesnt have to be a virgin, it wouldnt bother me. Thoughts/Opinions? I'm an 18 y/o male in college.
