Your rampant desire to talk about little else but sex can't help but leave the impression there are some serious issues you have in that regard, i.e. addiction. Have you considered getting counselling not just over this but even in your desire to go back into something so wrong as your last relationship.Find a good therapist Butalbee, it will help.
What one person considers to be an "addiction," is considered by many others to be a blessing. Is there such a thing as too much sex? No, as long as it isn't causing you to live in a cardboard box behind a shopping center. Even then, as long as you're happy there, it's fine!
Therapist? I think so, but not the type presumably referred to in the above quote. Butal needs a therapist with a very "hard" approach, one that will satisfy her heretofore insatiable sexual appetite. A professional license is optional.
