fshiguro toji/getou suguru

Geto Suguru was an omega. He was hormonal and horny all the time. It was a natural bodily function that he couldn't help. He did not choose to be born an omega. He did not enjoy being horny all the time.He liked to have sex. He had itches to scratch. He couldn't help it. He invited Gojo Satoru to be his friends with benefits. Originally, he only sought sex. He did not plan to fall in love or a whole package of romance.Things were great until it became ugly. Why was it wrong for him to like sex but not for the alphas?
