I don’t feel anything when he touches me

I literally don’t feel anything when my husband touches me anymore.

We don’t fight/argue. We have a great relationship. I’ve struggled with depression after our third was born. Our first was stillborn and I was only 20, second was preemie and third was born at 37 weeks exact. I feel like I have a form of PTSD or something from our first son being born.

I don’t feel anything when he kisses me/tries to be intimate.

I’ve been on/off lexapro and it doesn’t feel like it works. Wellbutrin was awful for me.

Please send suggestions/recommendations.
