5 years together, virtually sexless, he is bi-ish (Need Advice)

[TigerLover]

Personally I'd say go open or get out.

I know your life is tangled up with his and separation is difficult but you can't live like this forever, if he's not going to satisfy your sexual needs then this relationship is living on borrowed time anyway.

Besides it comes to something when a 23 year old gay man has the same sex life as a 55 year old married straight guy. This is, carnaly speaking the prime of your life and you'll regret it if you waste that.
