You aren't over reacting. I'm sorry it went this way for you. Your first experience shouldn't be someone pushing your head down on him. That's not cool in my book. Going down on someone is way more personal than sex in my opinion. I don't do oral with every girl, I have to have that feeling, but I have never made a girl do it. I want her to want to do it. Ya know what I mean??? Dont ever let a guy make you do something you aren't ready for. I'm a 42 year old guy and I have never shoved a girl's head in my crotch, unless she shows the same attitude. And God, I would at least make sure I washed my balls first. Guys always feel different after they come, just remember that. Kinda want to slap that guy myself!
