I think it's honesty, first and foremost.
Sex is pleasant, it's ingrained in all living creatures, human beings though... we tend to make it a sport, we have the ability to break down the act into parts that reduces it to its components. But it means different things for different people.
And so, I personally began with those two questions, first... it is pleasant and not evil, but it can if allowed to roam freely in my mind and my actions, turn me into someone who can be evil, but I will not succeed by merely ignoring it. Second, I had to determine what it meant for me personally.
What meaning did I attach to the act? it was more than physiological satisfaction, I attach emotional meaning to the act. And it wasn't always positive emotions, as it turns out. Sex can also be an outlet for fears, insecurities, control, violence and so much more.
Having those two in mind, I decided to find a way to make its presence in my life work with my overall goals. In practical terms, I found a way to find release in a way that wasn't overtly indulgent, but not completely repressive either. It is a drive comparable to hunger, and starving can lead one to make poorer decisions when seeking food, but then there's also the idea of fasting. Anyone who's gone shopping while hungry can attest to this statement.
In that sense, I treated it somewhat as food.. sort of. What I mean is, to satiate that drive, with as clean an impression as I can, instead of it being associated with fears, with insecurities or misery.. which I think sex can be associated with, one only needs to look at the varied amount of fetishes out there to notice, I seek to associate it with intimacy, vulnerability, beauty, creativity and things as such.
In this sense, porn, while extremely stimulating, can be a source of suffering and probably one of the worst types of impressions one can use to deal with the sexual drive, in my opinion, like fast food if you will. Because, in my opinion, it stimulates the brain and your mind in the way a lie would, empty and void of any real "nutritional" value.. empty calories, and probably toxic.
And find one's rhythm, everyone has a different rhythm, a different metabolism so to speak, and finding the healthy balance is crucial, restricting food for two individuals with different metabolic needs, will have different results and probably harm one of them. So that personal knowledge and self awareness is key in my opinion.
So, long story short, it's a very personal quest for balance and pragmatism in order to remain functional, sane and in harmony with oneself. Ant there's plenty to discover I believe, specially if one lives alone and doesn't have someone to explore that dimension with, which would probably be optimal, the next best thing is self awareness in my opinion.
In that sense, that self awareness could lead one to understand how certain practices surrounding the sexual drive can become harmful, and with sex.. as with everything really, that maxing of "First do no harm" really applies, and that not only applies to others, but also to oneself I think.
I hope the above made sense.
