Aside of the personal level (that, of course, means a lot too), experiments (involving people doing nothing, running, yelling at each other and watching soft porn in different combinations) have shown that physical excitement is interpreted according to our current cognitive state. “Huh?”, you might say, and I say, “Yes – if we get our body going due to anger, we can enjoy the excitement sexually if we think about sex”. Of course, different people respond differently to anger, and for many this can be a serious turn-off.
