Taste of sperm

Related question: Has anyone else noticed that when you kiss your GF/Wife right after she's been sucking cock, or if she has cum on her lips, her lips are a cooler temperature than if you were just making out normally?
Not my experience. Her mouth seems warmer and a little saltier when I taste her as I call it cock breath.

No and I think it is almost impossible.
In my case my wife enjoyed to cum kiss me. I didn't like the taste but each time I was very aroused. So no time to notice this.
