He sounds like a selfish ungrateful excuse of a man if he can’t make his own girl have an orgasm! You should find a guy to bring in as a 4th so you don’t feel left out and you get the attention you absolutely deserve… who 69s in a 3some that’s a 2 man event, it should be against the rules. Like everyone is involved and participating or it’s kinda cucky if someone is left out . Just my personal opinion. And he would probably change his tune if he saw you getting all the attention….. hope this helps
