After dealing with exclusively 7s for a while, I recently started exclusively 8s and 9s as I was tired of the lack of manners and just generally getting bored with them. I immediately noticed a lot more submissiveness and a lot more manners/trying to impress me. Sex is more intimate too, and I find myself doing less 1 night stands and more spending a weekend with a plate of straight sex and great times then doing it again the next weekend with a different plate. There's also a lot less ghosting/hassle to make plans. I also wonder if this has to do with a subconscious boost in smv within myself too, but I doubt it as I've been swallowing the pill for a while now.
