Good post! I agree about the points you made on sex addiction and I think it's great that someone is talking about it at least!?
I think all users replying to you don't understand that their actually on the wrong because the real issue is not about your topic it's that it's not technically a theory: it's speculation that's unsupported. For example...
'A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.
"Darwin's theory of evolution"
synonyms:hypothesis, thesis, conjecture,supposition, speculation,postulation, postulate, proposition,premise, surmise, assumption,presumption, presupposition,notion, guess, hunch, feeling,suspicion; more
a set of principles on which the practice of an activity is based.
"a theory of education"
an idea used to account for a situation or justify a course of action.
"my theory would be that the place has been seriously mismanaged"'. Quote from Google.
Notice that your post seems to be just a hunch rather than a strong theory about sex addiction. I'm not attacking you or your post: I'm helping you develop awareness of your ideas about addiction and sex addiction. Because of this, the other users who posted have posted on assumptions of your original posts and the following replies made.
Also, I like that your post contains other issues that seem to correlate to your topic; scarcity of resources, increase in competition and social media addiction e.g a selfie. Feel free to add another issue or correct me if I'm wrong about my list.
I can agree that those issues can effect sex addiction, but I believe that the points you made to support you're 'theory' are assumptions. Scarcity of resources? We're in the 21 century, in the age of information. Increase in competition? Actually this is good! You're improving as you're dating. Perfect men on social media? There's also perfect women that men see on the internet which gives a false sense of expectation when it comes to real interactions with women while dating!
Now I'm going to give my advice to you based on my quick read of your posts. I can't avoid making assumptions about you and your specific problems with this topic so feel free to correct me if I'm wrong:
You're a virgin and are interested in sex but you don't know how to date.
You're a porn addict, regularly materbated to porn and is feeling insecure about dating women.
You were bullied by girls and you feel a deep insecurity to women yet you need them.
You were rejected by your crush and is now worried about reliving the pain of rejection
You were bullied by 'cool boys' a grade or so above, hated/jealous of how they were idolized by girls and now you're older you're worried about being more aggressive to women because of how that makes you a bully.
For point one: journal you're experiences with dating and sex and make a commitment to learning about your sexuality.
For point two: introspect about this addiction and learn as much about it and it's causes.
For point three and five: Shadow work, meditation and/or therapy.
For point four: Feel into the rejection, let it go and continue dating!
There you go! Hope this is really useful for you. Good luck on your journey to self actualize.
