Can someone who is Bisexual have a monogamous relationship?

I’ve dated a couple of people that were Bi and was cheated on with other men

Strictly on man and one woman.

What about fetish? As long as it doesn’t do damage to the relationship and it’s kept in the bedroom

Do you feel it’s wrong for couples to use toys? After I thought about it, you’re right that fetish is escaping reality just as much as watching a skin flick
