Heavy metal seizure

I've got cerebral palsy that makes me flinch at sudden noise. I grew up with folk music and love it. All of a sudden I hear screaming vocals. It was my folk-music hating friend. I've heard those sort of vocals before.

He saw my reaction, he said I was pulling faces and he'd seen that face on PornHub. I shifted about, I clenched my wheelchair – my legs only seemed to weigh a few pounds and they started tingling and throbbing, they had a little heartbeat down them. they didn't hurt which is very unusual .

My talking-through-cotton-wool voice got worse. I muttered something to myself. The tingling got so bad i had to close my eyes, my whole body shook, all I could gasp out was “ah!...AHH!”.

It stopped and I burst into tears, asked said friend he had turned his music off, and told him that whatever had been happening it was the nicest thing ever and went to give him a big hug. He jumped away in surprise.

I've never had sex – hell would freeze over before I did that with HIM and the feeling is more than mutual – I can't move anyway. He teases me about it all the time. Any ideas?? is it the shock of the sound?? Is it the person playing it??
