Will will be open to hooking up even if you don't lose your virginity, actually. He just wanted Connor to take some time to think on it before rushing into anything. He knows that after meeting more people, Connor might decide he wants to lose his virginity another way. Connor wasn't exactly thinking clearly during that conversation 😉
There is going to be some very, very hot Will content in the story update after this one, but not a full hookup just yet - it'll be hookup-adjacent, more like the scene with Owen vs the scenes with Marco or Leo. It'll make sense why once you play it. But I promise I'm not gonna make you wait too long before the option is available 🙂
