Just taking your OP at face value and what little I know of your recovery I'd say it's totally possible you could be substituting one addiction for another.
It's a "brain thing", essentially. It is a type of 'high'. And yes, there are actually recovery groups for sex addicts that are along the same lines a AA, NA, OA, etc. There is nothing wrong with sex; it was created by God, just as there is nothing inherently wrong with a glass of wine which is derived from grapes that were created by God. BUT, anything can be done to excess and when done in extremes can have bad consequences.
When doing an "inventory" about your sexual behaviour (s), perhaps you need to ask yourself if there would be unpleasant consequences as a RESULT. Looking at it from that angle might help. Could you get an STD. Could one of your sexual partners decide they want to get serious with you even though all you really want from them is sex and a little companionship. All ya gotta do is watch that movie "Fatal Attraction" once to know that getting involved can lead to more than you want(ed).
