Okay, this will be a Mark Sloan x Derek Shepherd Sims thread...
Intro: I downloaded a Shepherd household one of my friends created. I started with Mark and Derek as teens and their relationship set as just "household members". The plan is to do a friends-to-lovers sort of thing.
I wanted it to be a slow burn, but they didn't want that. So they've already had sex (I have Wicked Whims, and one feature of that mod is that teens can have sex) and their first kiss.
Right now, I'm building up their almost-full friendship meter, and I usually just let them do the romantic stuff autonomously. The romance meter is over half full.
I'm not having them be boyfriends yet. I want them to experiment and deny their feelings until both relationship meters are full. I have an LGBT+ mod that lets you set their sexuality and come out to people, so once I want them out of the denial stage, I'll set their sexualities.
Anyway, that's where they are now and what I plan to do. I'll update in this thread while I play :)
Oh, and Mark seems to be a sub while Derek seems to be a dom, haha.
