I find that the taste of soon frozen semen is the same as fresh, but it isn't as thick. This isn't a surprise, because semen will quickly go from thick to thin even if it isn't frozen.
Whatever you do, don't leave it sitting around a while before you freeze it. Semen exposed to air and room temperature gets a strong, unpleasant flavor.
