Not in this version, but you can still increase your dick size by using items from the supermarket.
You get 5 cm aka 2 inch starting size, smurf-kun. This is because in new updates the bigger your dick is, the more money you can ask for when whoring yourself out. I will add character presets like in elden ring to get different starting stats and abilities to account for this though. For example the basic current MC as an all rounder, a more feminine mc with lust attack focused build and maybe a more masculine mc with strength focus.
