Well,
Man Sperm: Salty but smooth
Dog Sperm: Stronger more bitter and much warmer than human Salty and Tangy
Large Breed Horse Sperm: Not as salty as human, warmer than human so lightly salty and has a grassy flavor
Miniature Horse Sperm: Warmer than human with Salty and grassy flavor
Shetland Pony Sperm: Slightly less salty than human and warmer too with a very strong grassy flavor
Donkey Sperm: Warmer and slightly saltier than human but smoother and richer tasting with very little grassy flavor.
So which do I prefer is a hard question because I've never done a side by side comparison. As you can see above the equines are all a little different. It's that way with men too. White guys, Latin guys, Mexican guys, Italian guys, and Black guys all taste different too.
I can't really decide - I just like it all.............. ?
I like the smell of grass so I must be in for a treat. Thanks for those descriptions - very helpful.
