Hi it’s me I’m the problem it’s me

Me again :( mom of two who has been on antidepressants for 4 years now. Husband wants sex once a week and I know that’s too much to ask but I just don’t want to have sex.

First it’s he wants sex once a week. Then I do that and now he wants me to dress up on lingerie then tonight I initiated it for him, put on the outfit he bought then he wanted foreplay. I tell him how I feel and that I’m just never aroused and it’s just ALWAYS something else. I’m never good enough.
