I don't want to plow my pregnant wife-what's the big deal anyway?

SO she's a little over five months. It's not that I don't love her-I do, and I'm looking forward to being a dad, it's just that while she's preggers I'd rather keep the boys under wraps. She's growing, sprouting, leaking, her once little feet look like rib roasts now. I just don't want to plow her, but now she's getting all defensive, thinks I'm looking at and **** like that. Snaking the drain when your wife is pregnant is like putting gas in a car you already wrecked. Anyway I can't be alone-anyone else feel this way>?
