Intimacy Advice

Hey ladies! I’d love some advice if you have some go give...

So I don’t know how everyone else feels, but I feel fat, exhausted, uncomfortable & well pregnant. I have 2 girls (2 & 1) + being pregnant, so I’m tired a lot. Being intimate with my husband is literally the last thing on my mind right now, mainly because I’m exhausted, but also, I’m just not in the mood. We currently can’t have sex because of my placenta, so he’s not concerned about that, but he just keeps asking about fooling around or showering together (hand job) & I just keep telling him no. I don’t know how to further explain that I’m exhausted & pregnancy (for me) just doesn’t make me feel all hot & bothered (per say). I’m at a loss right now of what else to say, so I thought I’d see if you all had some advice. Thanks!
