You had safe sex and clearly your only problem is your guilt over the event. I'm not a counselor; you're on your own to deal with it. The direct ansswers are 1) The risk was zero if the condom was intact; any risk from the way it was removed is too low to worry about. 2) How can I know what the condom looked like after the event??? But if it had broken, it would have been obvious.
No prolonged discussion, please. If you and other users want to continue to exchange thoughts to help you with your anxieties, please take the discussion over to the HIV Support forum.
