To be sure, the safest sex is sex with yourself. "Masterbation: sex with someone who really loves you." So I guess this is where the dildos and dolls come in. (No pun intended.)
Would you like your dildo in glass ("Note: These are made of Pyrex, but like all glass sex toys, please exercise caution when handling it, as even a small nick in the glass will make it unsafe to use.") or would you prefer something vibrating and cartoon themed? Or are you looking for something very expensive and anthropomorphic (and creepy)? Of course, you can always do it the old fashioned way. Don't worry, even if you do grow hair on your palms or start to go blind, they can do wonderful things with lasers these days.
But remember, just because it is the safest sex doesn't mean you shouldn't be careful.
(All of these are pretty much NSFW)
Excuse me, I need to go wash my eyes now.
