Everytime I take cough medicine such as tylenol night time, my cock gets super engorged and feels thicker than normal, I can't cum for a really long time, and when I do, I have extremely power orgasms, so much so that afterwards I just pass out from being completely drained. I looked for side effects, searched the net, and now I am inquiring here and have yet to figure out what in the medicine causes this and if anyone else experiences the same.
