I’m really uncomfortable with you conflating this man’s domineering behavior with his physical body. I don’t necessarily agree that he was under any obligation to tell you that he had a micropenis. It’s his body. It’s his right to decide to disclose.

You’re also blaming him for your own choices. Awkward situation? Definitely. But you act as though he cleverly manipulated you into sex acts you didn’t want. In reality, you consented to engage in sexual activity with someone you found repulsive for a myriad of reasons. You should work on your own boundaries, and quit blaming vulnerable others for having flaws.
