Absolutely Humiliating

I thought I had finally found a woman who liked me and accepted me for who I am, but yesterday she shattered the little confidence I had left. During foreplay she jokingly said that she wanted to suck my "hen". I asked her what she meant and she explained that because I have a small penis it isn't a "cock", but a "hen".

It instantly ruined my mood, I left the house and now idk what to do. She's been ringing me since I left last night. She knew how insecure I was about it, yet she chose to ignore my feelings for a cheap laugh. All the suicidal thoughts I had are slowly coming back. I really don't feel like living anymore.
