Well I was going to respond, but I feel like BSB really said it all!
I guess I'll just say that I love female condoms! I really do prefer them... they feel so great! And one size fits all.
Oh and, I like to keep the inner ring in for using vaginally, because it locks the FC2 back against my cervix, and as the action proceeds, the condoms gets warmer and warmer, and presses more perfectly into all my crevices, until it doesn't even feel like it's there at all! So amazing.
I know hear works great for ass-fucking if the inner ring is removed, although I have never tried it that way personally.
