How old was the boy? Did you teach him things about how to please a woman?
Really? It's an expression, he was a young man, younger than me, not a literal boy. I have a need for attention, I am not a pervert.
I don't know you and have no reference for your phrase "boy next door" other than the literal words used. While I didn't mean to offend, it was an honest inference based on the words you chose. It costs no more to write "young man next door" and leaves no doubt about his age.
Were you then a successful Mrs. Robinson, seducing a younger man you and your husband knew socially? Or was he the aggressor, sensing the sexual longing in his more mature, married neighbor and taking advantage of the situation to sate his youthful libido?
