Yes this is why im skeptical of guys with super high lay counts. Im like " so you were never in a long term relationship bro" . Unless you cheat like crazy LTRs take you way out of the game.Being surrounded by prime quality material certainly helps.
I knew a guy in Costa Rica that had 5 girlfriends. I met 3 of them. One was hot, the other 2 were not my cup of tea at all. Personally I'd have just taken the hot one.
Another factor is LTRs can take you out of the game for years. If you never have a long term relationship then you'll have a high lay count but that could be a sign of some kind of problem rather than skill. Case in point: Rooshv.
