Why do guys enjoy it when girls make out?

I have come across so many situations where a guy/guys want two girls to make out, or touch eachother in some sort. I actually don’t think I have ever come across a male who has said that he would not enjoy that. Why do guys like it and think that it’s hot? I ask them, but they never really have a reason.

Anyone can answer.
but guys out there, do you like it when you see two girls kissing or touching eachother or something like that? If you do, why? If you don’t then why not?

I know it’s kind of a weird question, but I’m curious(:
