A small bit of backstory. My long term girlfriend has a fairly low libido that’s well below my own. She tries her best but I’m often left feeling unfulfilled.

On top of that I’m a little bisexual (much prefer woman but some guys do it for me). Is there a good way to introduce this idea to her? I’ve thought about watching porn together and suggesting bisexual porn to see how it goes.

If I’m honest I can’t see it going well. It’d be such a shock to her that I’m not sure we’d recover from. Maybe this is something best kept to myself?

TLDR: want to tell my gf I’m bisexual but don’t think she’ll take the news well. Advice?
