crazy. Every woman starts to look good to you. Every woman you see, you immediately thing about sex with her and how her vagina would taste and feel. You want to cum so bad it hurts some times. You may even start thinking about settling for a BJ from another guy even know you are not into them. Something is on the inside eating at you trying to get out. Usually at this point when I start getting hard and it is warm, I have to go somewhere and jack off. Usually after I cum, I kinda feel dirty and guilty, but usually after a while, I feel ok. I am a sex addict and I feel like this on a daily basis most days. I can go JO and be ok for an hour or so, then all I think about is sex. When I see or talk to a woman, her vagina is all I am thinking about. With exceptions of course. Not into family, minors, or old grannies or anything gross like that, but all other women are fair game. I hope this answers your question.
When we are aroused, our penis feels the same way your clit does when you are aroused. That’s the physical explanation.
