My husband said he wants to be cucked, should I agree to it?

Hi I’m F26 and my husband M30 we have been married for three years. The other day he said he wants to watch his friend fuck me and that they already talked about it. I told him I needed to think about it.

I have no issue with this and think it would be really hot. His friend is also very attractive. My only concern is my husband won’t actually enjoy it as he thinks and it could cause problems in our relationship. Should I agree to this?

TLDR: My husband wants to be cucked, should I do it?
