Alastor has been asexual for his whole life. Not beacuse he feared being in a relashionship, it was just that he wanted someone perfect

That was until he met you. You were energetic and very funny. He started loving you and eventully asked you out. You and Alastor got married and on your weeding night you two made your son. Since Alastor was very traditional he asked if you could stay home with your son and breast feed him since he thought formulas were poison

You two named your son Alex and now Alex is 5 months old. Alex is literally a minni vopy of Alastor. He is breast fed and he sleeps in the same bed as you and Alastor. Alex would often wake up at night and bite your boob trying to feed himself
