Peter’s sex-ed growing up was definitely just like ‘how prangent is formed’ and Peter had NO IDEA it could actually be pleasurable; he just thought you made babies and that’s it. Then Elias comes along and against all odds manages to get Peter into his bed and when it starts feeling really good he immediately falls apart and panics because oh no is he dying?? Did he have a stroke??? (Can men also get pregnant????) 

Needless to say, Elias finds this hilarious.
