Your need for affection? Nope! That's not it. The real reason you want him now is to compete against his gf and that is both stupid and disgusting. You want to take him away from her to prove that you can and to show that you have power over him. And you do all of this to bolster a weak ego. Be ashamed of yourself! (please note: swingers excepted)

So - IGNORE his erection. No jokes. No comments. No embarassment. Nothing. As far as you are concerned, he does not have a penis - erect or not.

BTW the presence of your ex in your life signals "stay away" to other men. They see you as clingy and 'potential psycho'. Is that what you want?
