Perhaps this could be an interesting and useful topic to discuss here. Something that many of us HD folks kind of know about ourselves but perhaps turn a blind eye and ignore it. But what exactly happens to the HD folks here that you might describe as negative side effects when opportunities for sex are too abundant? Here are some models:
This is the part of a relationship that last for perhaps a few months to a few years in which sex is very frequent, but we all know it is just not sustainable. Most of us wish it were, but eventually life and responsibilities catch up to couples and they simply no longer have time to go at it multiple times a day. For whatever reason this period of a relationship seems exempt of any negative side effects of too much sex.
COOLIDGE EFFECT https://en.wikipedia.org/wiki/Coolidge_effect
is a psychological theory that suggests that sexual interest decreases over time in monogamous relationships. Efforts to increase sex within monogamy once this begins to occur may only serve to increase negative effects of loosing interest and make other partners begin to look more and more attractive. The best analogy I can come up with would be to force feed someone ice cream sundaes until they can no longer stand them. Then this person can't help but to notice all other foods that are different from an ice cream sundae and start desiring them.
OVERUSE OF PORN
We all know this has detrimental effects on relationships. Many heavy porn users find themselves so overstimulated that they can no longer enjoy "vanilla sex" that it just simple and natural. Must often sex must be very aggressive in order to attain climax with a partner, or anorgasmia may even occur (unable to climax). Many times heavy porn users may even feel complete lack of interest for their partners.
OVERUSE OF NOVELTY
New ideas and novelties can create too much extra excitement, and it is possible to overuse novelties to a point that sex becomes so unnatural that one's sexual orientation will destabilize in attempts to continue seeking out even more novelty. This is when heterosexuals start to become curious about forms of bisexuality and homosexuality solely because everything else is known/boring and this represents the only remaining way to seek out more novelty. This can happen to some men and actually cause a crisis thinking that somehow their sexual orientation has now been changed permanently. But if all use of novelty is discontinued, things will return to their original sexual orientation.
POST COITAL DYSPHORIA
Is the idea that what goes up must also come down for both males and females. Obviously the enjoyment of sex creates a euphoric feeling that our bodies simply can not sustain. In the event the body enjoys sex too much, afterwards one can be left in somewhat of a sexual hangover in which the body needs to replenish our "feel good chemistry" and we become susceptible to pain, loose our patience, and become irritable for no valid reason. Perhaps this is why people that are blessed with overwhelmingly exciting and passionate sex, find the rest of their relationship filled with constant bickering and arguments over nothing. Couples aware of this phenomenon sometimes find that it can be completely avoiding by engaging in sex that is gentle and relaxed as opposed to always being very rough and aggressive.
This is when you have had really great sex and your body does not want to come back down from that high, so one becomes sexually aroused immediately after sex in an attempt to avoid pain and discomfort of an oncoming episode of post coital dysphoria. While this seems exciting, it is a sign that one is about to experience stronger than usual withdrawal effects while they resume normal activities.
Those in the BDSM community are aware that really rough sex often requires aftercare. This is a period of time where one finishes experiencing being pushed beyond their known sexual boundaries, and already know to anticipate what it needed to come back down from that may not always be easy. Sometimes rough sex for these type of individuals will leave certain areas or muscles noticeably soar for a period afterwards.
While most couples may not experience these things, those of us HD folks have likely encountered some of these to a certain degree regardless of if we are aware of it or not. But the key question to ask ourselves is what negative impacts to these side effects have on our marriages?
