How to get my men to want me.

I’m in a relationship with 2 men. They are both straight. We all live together though and we all agreed to this relationship.

Neither of them ever want to have sex with me anymore though. I’ve caught them both jacking off several times though. Like unless I ask them to fuck, it never happens and sometimes they still tell me no.

I need some tips on how to get them to want me. I can buy lingerie and maybe some toys and offer to try new positions, but they still don’t seem interested. Idk what else to do.
