Saw another post and got my mind goin lol. Okay so im gonna be starting birth control soon and i know some say they dont work 100% if youre overweight. Im 5'3 and i weigh 204 (trying to lose weight). So if i go on it should i stay away from him ejaculating in me? Or do you think itd be fine? I just had a baby so im not trying to conceive any time soon. Im thinking of the patch,pill, or nuva ring.
