Should I hook up with married men?

I’ve recently have been exploring sex more and I don’t have much experience. I’ve only had sex with 2 guys and less than 20 times. Recently an older Gay married couple hmu and were looking for friends and a 3rd. They have had a couple 3rds before. I’ve been getting along with both of the guys very well. They are both 35 and I’m 24.

They messaged me with the intent to have a 3 some but we’ve only chatted so far. They have planned time that we can all spend time and have sex in a couple weeks.

Does it sounds like a good idea. I think they are both hot and I’m not worried about my safety or anything. They are nice guys. My friend urged me against it but I think it might be nice.

Should I not do it?
