I've been thinking of adding a little bit of quality vodka to stored semen.

I've done this before, but only with fresh semen or after I thawed it. My idea here is to add it to fresh semen before putting it in a freezer.

The idea being the alcohol will keep down germs that could form (from saliva for example) and maybe keep some of the cum consistency since it would not entirely freeze. (Alcohol doesn't freeze in your household freezer)

Also, if you really like the flavor like me alcohol could do what it does in all alcoholic beverages, intensify flavor and aroma.

Adding more vodka will make it more watery, but also give you a buzz so the choice is yours.
