Sexy time blues

I feel like such a bad wife because I haven’t been able to please my hubby as much as I’d like too... I’m 8 months pregnant & the past few months I haven’t felt myself, I’ve struggled with my weight & so far I’ve gained 40-50 pounds during this pregnancy so I feel unattractive.. I want to be able to please my hubby & make him feel good but I’m also at the point where everything hurts and right now I just feel like such a bad wife for not being able to please him sexually... I don’t know what to do
