Question is about my boyfriend. He is 22 and in very good shape, not overweight or had any previous medical conditions.

During intercourse last night, my boyfriend stopped, Slumped over the bed to pause. He then fell off the bed, passed out and fell on the floor on his back. He made a sound like he was snoring, so I reached in his mouth to make sure he wasn't choking on his tongue. His jaw was locked, half open, and that freaked me out more. I threw water on him and his eyes opened but he wasn't responsive. I felt for a pulse and he had one, and I don't think it was rapid. I kind of pushed hard on his chest and watched his eyes as they became responsive again. He then got up and said he needed to throw up. (The whole ordeal probably only lasted 1-2 minutes.) He didn't throw up, but was nauseous just the same. After 5 minutes he was as good as new.

He tells me that he fainted from being overheated. He said he felt his head swell and knew he might pass out. He said that he just felt as though he fell asleep and he had no headache or any other symptoms after the fact.

Was this a seizure or Fainting? Should he go and get tested for epilepsy?
