This is an interesting thread. When I started coming here and really trying to understand myself and what was happening to me when chicks were around, I thought there was something wrong with me. Women exhausted me mentally, I would be on top of the world then the next day down in the dumps. Couldn't concentrate. Couldn't do anything productive until "I saw her again".
I saw all these posts of how that was AFC and unfortunately for awhile there, I thought what I was experiencing was unnatural. That it was only me. That other guys didn't get these feelings too. It's important to know that it is something you just have to learn to handle and work through, that it's not "unnatural" (you're a part of nature and it's happening so it's natural) but it's not necessary either.
