What does everyone do when they've ejaculated and you've made somewhat of a mess? Do you wash your hands once or more than once and vigorously or..?
If I manage to ejaculate into my FleshLight, I take it into the bath with me & it gets a good washing there, otherwise I normally wipe everything with an old towel, kept specifically for the purpose. If, however, I've been using lube, or have an excessive ejaculation, leaving everything exceptionally wet & sticky, then I either give it a wash or take a shower. As far as hygiene is concerned with standard masturbation, there is far less bacteria to be found on your penis than on your hands, and (unless you have OCD) you wouldn't feel the need to wash your hands after shaking hands with someone.
