I’d fuck them for pleasure and maybe even date and I have one long term but they’re not marriage material unless you find a one in a million, even then you’re looking at either long term health issue and probably not able to have kids etc. You see how fast being that big ages most women. They’ll look like shit by 35-40. It’s just not a good long term lifestyle and most of the really big ones I knew lost the weight in their 30s. If you plan on being single long term or just hooking up do as you please but you’ll miss out on a full life. Pounding fat plushy women is heavenly but you’ll find most of them are either mentally ill, raging narcissists, or hate themselves and you won’t save those one from hating. A dated a woman long term who was high 200s until she found my porn stash and then turned herself a 400lb fuck toy only to wake one day and blame me for it. Anyone who’s willing to do big gains has mental problems, and the ones who are huge and just accept it will either die young, turn into a goblin, or lose it all and then turn into a even worse mental case.
Settle for 200-350. It’s more than enough and lots of normal women are in that range.
