My experience, sperm will taste good according to the mindset a person can be in. If swallowing turns you on immensely, the strong, musty smell and taste definitely can be good. It is an acquired taste, just like a beer lover's acquired taste for beer. I believe if anything turns you on enough it can be good in its own way. It is learned behavior that can definitely be good. Just like licking an asshole, the first time I thought about it I was repulsed, but now it is a huge turn on. These things become something in time you may have never thought they would be.
