Both my kids (6 and 3) are aware that you can marry anyone you fancy - man or lady and its totally fine. I did point out it was a bit more tricky to have babies in a same sex marriage, but it can work out and they are still parents.
Its just typical of the DM to hint that the mention of same sex relationships means some lefty teacher tell little Jonny all about he intricasies of bumsex or the like?!
