When do you know your addicted to sex?

Well, thinking about sex constantly is normal. I feel that way(29 year old male). Having those thoughts affect your normal behavior is odd. I would talk to someone if you have the means. For example: if you were fooling around with a woman would you be able to stop? If your answer is "no" you need to run to the doctor.

if you have to ask then the answer is yes

So you're full of juice. This is a good thing.
Getting it every day is a good thing.
If it's consensual.
Is it consensual?
Talk to me.

its ok to feel that way - the desire for sex is actually genetic and its perfectly normal if your partner has no problems whatsoever. But with that said (i personally) feel that having sex every single day is a bit extreme
