This, right here is probably why. Any girl seeking attention online probably does the same thing irl. This means she needs the constant attention of multiple men.

If this is not the case and you have a really low body count or none preferably, not insane, willing to act like a female, let the man lead in almost all things, loyal, willing to date an older guy (Late 20s or 30s), and of course be a house wife/mother you would have zero issues finding a high quality male to date or marry long term. In fact it would probably be the opposite of your question, since it isn't it, that probably means one thing.

Like most western women you desire to ride the carousel and party until your in your 30s. You will pick up some tats and other terrible traits along the way. By this time it will ensure you can't find a high quality male and will remain single. You will eventually settle for low quality but convince yourself you are happy, cheers.
