Well, this is a true story which I know. My friend's dad is gay (single, divorced)…he himself being gay too and quite hunky. He does not do things with his dad (lol just to mention) but he told me once where his friend suddenly came over....but it was to look for his dad not knowing that the gay guy was actually his dad...
They live under the same roof but he told me it was really awkward when someone you know comes knocking at your door, for a bootycall by your dad (lol total awkwardness)
