@23Flotsofquestions,
Every antidepressant I've ever heard of mentions "sexual side effects."Usually this means "it destroys your libido, at least while on it." Once you're off and have completely flushed it from your system (can take days or weeks) your libido returns.
Clinical addictions are usually defined as problemtic-behaviours. With masturbation then if you masturbate in front of others, at work, in school, or otherwise at times and in places you shouldn't, it's not addicition. Frequency isn't a good guide for addiction since everyone's libido can be different. What's "a lot" to one may not be to another.
I masturbate upon rising (great incentive to get out of bed on chilly mornings,) and before bed (climax and natural drowsiness is a great natural sleep-aid) typically. But don't seek sexual relationships.Prefer to 'get 'er done' then do other things.
