I agree with the previous poster that it is a question of higher sex drive, not an addiction. Moreover, sex addiction has not been oficially recognized as a diagnosis - it is not included in medical manuals of diagnosis (DSM IV, ICD etc...). In my opinion the label "sexual addiction" has become mainly a part of a new "fashion trend" among popular psychologists, especially in the US. It reflects the trend to look for addiction almost everywhere where there is a strong desire and dissatisfaction if our needs are not met.
From my own perspective, we could speak about something like addiction for example if we could not control our urges to have sex, e.g we would get into serious troubles at work because we would run from the workplace to the nearest massage parlour to pay for sexual service or we would try to approach unknown people in public in a sexual way etc... something like an obsessive / compulsive behaviour. Another point is that a real "sex addict" would find it impossible to be satisfied after having sex, sexual gratification would leave him empty and probably as much "hungry" for sex as before, even if he / she could have sex as often as he/she wants.
Thatīs why I would prefer the term "obsessive/compulsive behaviour" to the term "sexual addiction". But the problems described in the posts above do not seem to be about any "compulsion", but they just reflect a higher sex drive. If you could have a sexually compatible partner in terms of sex drive (frequency of sexual activities, sexual preferences etc...), I guess that your problems would disappear and you could find sexual satisfaction quite easily and in a very healthy way. From my point of view, if you want to have sex once or more times a day, it is OK and it should not be called a disease, pathology or addiction. If you need sexual gratification before going to sleep, it seems to me pretty normal as well. (Maybe because I am the same in these matters...
