Bi flirting

I'm a 35m and realized I was bi curious a couple of years ago. After overcoming some internalized homophobia I'm feeling ready to actively explore these feelings.

I have a female partner that is accepting of this and is open to the idea of an open relationship. As I start to think about this next stage I'm curious to learn about how bi guys put them selves out there to flirt with other bi/gay guys and explore this side of themselves.

Bonus points if you have advice for how to take it slow and effectively relate the experience to a committed female partner.
