Exhibit A? NFL player Tim Tebow. His ex, Olivia Culpo, actually decided to split with him after just two months of dating because he was practicing abstinence.

"She had to break up with him because she just couldn't handle it. He still hits her up, but she just can't deal with the sex thing. He's pretty adamant about it, I guess," the source revealed. Yikes!

But to be fair, the sports hunk did admit that he's saving himself for marriage. In fact, when he confirmed it with reporters, they were so shocked that they couldn't come up with follow-up questions.

"I think you're stunned right now. You can't even ask a question. … I was ready for that question, but I don't think ya'll were," Tim said.
