Thats really outstanding for you. Its no doubt that you feel exposed and raw the next day. you really have to let go of your control to allow that.
Put a towel under you and enjoy it. Its a gift that you are giving to the guy. It doesnt make him a stud, there are techniques anyone can learn to 'force' it to happen, But that doesnt sound like what is happening. It just means you trust him. He should be grateful, not puffed up and crowing. Appreciate that he helps you feel safe enough to accomplish this.
and like nop said, dump any man who isnt mature enough to handle it.
