I am not bisexual but know ton of people who are, including my daughter.
Yes she always discloses it when she meets new people. She had long term (including one cohabitated)relationships with women, at least oneremained a good friend. So she wouldn’t be able to hide it from men even if for whatever reason she wouldn’t want to disclose. No men ever objected. Her current boyfriend is straight but his late father was bisexual, after his mom passed away his dad lived with male partner for years. So obviously he didn’t find bisexuality anything to fuss about. My daughter says no one ever cares. I believe her
In my understanding homosexuality isn’t as much about sex as about who you attracted to. I’d say it’s not wring pursue whatever with whoever as long as you are nice and honest about it. Sure if you like the guy, who not go for it?
