Hollow Strap On – Safe for Anal Sex?

So I’m hooking up with a guy I’ve been talking to for a while this upcoming weekend. I mentioned that I tend to get shy when I’m naked and in person with someone so my penis tends to get flaccid unfortunately.

The guy was totally understanding and comforting , but he did mention that maybe I could look into buying a Hollow Strap On to have sex with him with.

It would be my first time really using a toy like this for sex and I have a million questions running through my head. But the most important one is: would using this on my cock be barrier enough to have anal sex with him with? Like would i risk catching a disease if I use this on him without actually exposing my penis to his genitals?

Thank you
