My female bestie often asks if I want to make out with her. Surely that isn’t normal?

We have been close friends for around 4 years now and she is very pretty and always gets attention when we are out. She says she misses making out with people. She says it in a joking way but I’m not sure if she is serious because of the amount of times it’s been brought up. The most recent was when we were out and she asked me this in front of the guy that was hitting on her. The previous time was when I brought her coffee to work. It’s doing my head in. Would this be something she’s thought about before and would be down for?

I spoke to her recently and she said she only suggests that we make out when she’s drunk. I know this isn’t the case. But it’s still in my head that she wouldn’t bring it up and “joke” about it unless if she was somewhat serious about it.
