Hey everyone! I'm new here and it might be strange for a guy to be on here, but I am a worrier by nature and i'm trying to figure things out. My girlfriend and I have had sex using the withdrawal method for the past year with no problems. We both exorcise a lot and she is probably a little lower in body weight and is also hypoglycemic so her periods have never been regular. But she told me her period has not come yet and we have had sex twice this month, both im certain I did not ejaculate. Now, I know people will say the pull out method is unreliable, but I try and be the perfect use person when we use it (meaning I urinate each time to flush out any excess sperm). She has seen no symptoms yet as far as I know, but of course because she asked about it, I am beginning to worry. Any thoughts?
