What's wrong with me...

Try to solve it using emotions and common sense yourself, just to exhaust all of your options at home. I figure you're smart enough to figure out what turns you on and what type of mood is conducive to wood. I'm sorry, by the way, that you have anxiety or whatever. That shit is no fun.

If trying again doesn't work, maybe see a doctor for ED or something. If he says you're fine, then just keep trying to give yourself some self-applied therapy at home. If you go months without being able to fuck, after getting penile clearance from the dick doc, perhaps see a therapist after that.

Calm the fuck down and just fuck the bitch
