I went PUASA for that 38 weeks during her pregnancy. DIY & find FL if I need it.
I don't dare to try it afraid to hurt the foetus. Though my wife did tell me she wants it & horny but I rejected. Told her I don't want to risk it. My ordeal was paid off, she gave birth to a pair of healthy & beautiful identical babies gals.
Next year they are going Primary 1. Time flies...
