My boyfriend didn't know I had a snake until about 2 weeks after we started dating. We had just never gotten onto the topic of pets until that day. When he found out I had a ball python, he smiled really big. He said he used to have a corn snake and a red tail boa, but he had to rehome them when he moved and that me missed them terribly. He was glad to hear that I liked reptiles, because he is a reptile lover, too. One of the many reasons why I love him so much.
With that being said, the fact that a guy has reptiles doesn't make them more attractive to me. After all, I'm attracted to him, not his pets.
