You know, our hormones can't take our bodies over or make them do things against our will. I understand that you're feeling conflicted right now, but not holding yourself accountable for your own actions really isn't going to help any.
Is it normal to have conflicting feelings about first-timme sex? Sure, absolutely. Though my experience is most people feel conflicted because the sex didn't go the way they thought it would, which is usually a way that is LESS realistic than how these things actually go. So, chances are how things went for you were pretty similar to how any first-time sex would go.
The best way to get your mind off of things is to really think about and process them, truth be told. So, it's worth thinking about WHY you feel the way you do and doing what you can about it. For instance, if the regret has anything to do with nnot using adequate birth control or safer sex protection, get EC if you need to and arrange for testing in a while if you need to.
if it has to do with your relationship, call your partner and talk to him about it. he may need to do the same himself, you know.
But we make choices, we can't usually undo them. So wishing one hadn't done something one had is of very limited use. Really thinking things through, caring for yourself as you need it, and dealing with the consequences is far more productive.
