Should someone who is bisexual (but does not act on it) disclose this to their spouse before marriage?

I was having a debate with a friend about this because she knew someone in this position. She says yes, they need to be honest so the potential spouse knows what they are getting into and can refuse if they don’t want to be with someone who has attraction to the same gender.

Personally I say no they should keep it to themselves. It’s haram to normalize it anyway and if they have never acted on it and never will what is even the point?

Thoughts?
