No, at that point you do not know what the milkshake is, and unfortunately people have free will.
Athleticism needs to be high for you to make a difference in the sports you practice. It's a meter calculated based on a few different factors, you can see it in your character screen where you can see muscularity, plumpness etc. I've had games that were won when the bar was at like 15% somehow, and games lost at 60%. There are also some hidden variables that are given by getting certain events to trigger during practice.
checkvar: "$sport.started and $sport.rounds gte 3 and $football and !$football.starter and $football.proven and !$sport.playeringame",
Without you contributing anything to the match, the base stats for each school are used.
name: "Fighting Elks",
university: "Fitzcummings-Knueppel University",
longname: "FKU Fighting Elks",
ability: {football: 7, esports: 7, swimming: 7},
"Mongooses":
{
university: "Crestwood University",
longname: "Crestwood Mongooses",
ability: {football: 4, esports: 6, swimming: 5},
"Thunderhawks":
{
university: "Silverdale College",
longname: "Silverdale Thunderhawks",
ability: {football: 9, esports: 5, swimming: 8},
Etc. - so some schools are better at football, some are better at esports, etc. Against football 9, you'd have to contribute 3 to the skill check. I'm not sure what exactly would contribute to that, but as I said above, the game checks for certain variables that are granted during practice.
You might lose a few games before you get the variables, depending on what school you're up against. Just keep attending practice. I've also noticed an increase in progress by doing cardio a lot while I had swimming and was already maxed - the game keeps track of how many times you did cardio and weightlifting, so they may influence athleticism without explicitly saying so.
Player can, if you have multiple kinks and they're all met constantly, your arousal will go up faster than the npc's.
Alternatively if you successfully deny your partner orgasm, or if you just get oral sex and prevent the other person from getting off (i.e. they're not touching themselves)
Npcs can't cum multiple times, I've even tried editing the HTML rules for it. It's something related to the way "watersports" are implemented, even if they're disabled. Cumming once makes them "spent", which is one of the flags "watersports" checks for in order to trigger (if it's enabled).
