Does anyone else use the withdrawal method? It's been super effective for us and we've been using it for years. I always worry pretty much every month and this month isn't any different. I'm not really worried overmuch but we did something that I don't know if we've ever done. We DTD 2X in one hour and he didn't pee in between. Usually we make sure if we do that, that he pees in between to kinda flush out any sperm that might be still in the urethra but last night we forgot. Anyone know what the chance is that I could get pregnant from what little sperm, if any, would be leftover?
