Is monogamy synonymous will maturity? To not be monogamist is to be immature? I read some where else on this topic how other expressions of affection can outstrip physical sex in terms of emotional depth and significance. Many women & men have non sexual relationships with deep seated feelings outside of their marriage. Are they some how 'better' b/c they remain non sexual? I don't think so. Monogamy is not THE determining factor in a person's maturity....imo. If I found out my wife, I'm not married btw, had an emotionally charged non sexual relationship outside or marriage I would be more likely to walk than if she had a sexual 'flung'. Sex is NOT the end all many make it out to be.
