If I have given you a boner, an apology

If I have given you a boner and not a blow. I am sincerely sorry.
If I have given you a boner and not a plug. I am sincerely sorry.
If I have given you a boner and not a happy ending. I am sincerely sorry.

Maybe, just maybe, its practice for you to learn
when a boner is a curtesy from a pussy and
not always an invitation to getting down and dirty.
