My girlfriend at a bachelorette party, participating with the male stripper: Is it cheating?

No it's not cheating, it's a 'party' and just in the name of fun. It doesn't mean she has any real interest in the male, other than enjoying his 'performance'.

That would depend entirely on what the actual definition of "participating" is. Cheating is most often defined as establishing an involved and mutual emotional or physical relationship with someone other than one's monogamous partner.

I personally would be extremely surprised if in the space of a bachelorette party, someone was able to interact that much and that intently with a stripper.

Unfortunately its the same as a guy getting a lap dance when hes married/ or about to get married. Usually cheating involves gettin more intimate. Everyone is their to have fun, it is a party after all. If something sexual does occur then you can call it cheating and it would be on you to make the call. Since technically you would be the victim unless you did the same thing as her.

um i would say no........no shes not being intamite at a party with the stripper who's being paid to take his clothes off which is his job, like any other job out there
