It’s 3am, I’m 37w and I’m horny

My sex drive has a mind of its own now. Most days I’m not horny, until I just am. I hardly sleep at night anymore and today is one of those days. I’ve found it’s more comfortable sleeping on the couch then our bed. The couch is comfortable and lower to the ground which makes it easy to get off and on unlike our bed. Anyway, it’s 3am and I’ve been awake for about 2 hrs and I’m horny. So much so that I’ve gotten naked and went to try to wake up my partner but felt bad when he woke up complaining that he still having a bit of back pain and that he’s too hot. Usually I wouldn’t mind and I would still try to seduce him but he’s had a very rough day. Now, all I can do is be naked till morning and hope he wants some loving... and that I’m still in the mood. I can’t masturbate because at some point in my pregnancy it became imposible to orgasm alone and the few times I have it’s been extremely disappointing. However, when my bf does his thing to me with his “big magic wand” it’s a full body satisfying high that relaxes me to the point that I’ll pass out right after... and mommy really wants that now.
