Is my friend gay or he was asleep?

One day when i slept with my friend i could feel his penis pulsating. He was lying prone and he began to turn a little so that his dick will touch my thigh and it was pulsating. He was not snoring at all. Them he moved away from me. He flexed his knee and thereby his legs were in air while lying prone and he just brought down legs. He repeated it three times. Was he awake? If so, what shall i do?
