Threesome---well, they didn't mention how many
Pastime---nope

Well OK, what is too closely related ?

Your cousins----well they do share the half blood of you so it's probably not a great idea (and all of my good looking female cousins were a fair bit older)

OK, so we are at second cousins---geez, where is the relationship---how are they blood related to you-----do you know them----could you meet them on a night out and not know til they mention Great Aunt Mary.
