I have a really advid imagination and can get off in about 3 minutes twice daily by just using my clit.My addiction is to the point that Id prefer to masturbate instead of have a sexual partner since I know that I can get off faster and better!! Bad?

Twice a day is not much at all. But you prefering masturbation to sex can get a bit tough. Are you stilll a virgin or have you experienced both and then reached a conclusion that you prefer masturbation.

should throw in some self pleasure while you are having sex with a partner ... will make it doubly hot for both of you

I don't think it is necessarily bad, but why instead? Just get yourself off twice a day and also have a sexual partner. There is nothing wrong with getting yourself off when you have a partner or are married.

No doubt faster, but clearly you have not yet really learned how to enjoy a man.

If it's only twice a day it's not an addiction. I masturbate many more times a day than that sometimes, in addition to sex with my bf.

Oh, I don't know about bad, but don't you miss that huge, throbbing shaft sliding inside of you. I know, even if I masturbate, when there's no guy around. I really miss that sensation inside me, and that strong, masculine presence on top of me. I can get off quickly alone, but I'd rather take a little longer, and cum with that huge shaft inside me. Maybe that's just me, I love men, and I love taking cock.
