I don't even offer full sex so am probably not best person to answer but as no one else has and I am here I will say that I think a female condom femdom thingy is NOT as protective as you are still vulnerable to pick stuff up from his tackle on the outside of your pussy.  Wouldn't do it if I were you. Known as barebacking, and you will get a bad reputation.

Do a search for 'femidom', which is the brand name they were launched under in the UK.

They come inside it, and it stays in there until you remove it.
