The Youtube video was very informative for us female condom virgins. However, it is apparent that once inserted, it signals the end of DATY until after it is removed. So, if a lady starts the session with it already inserted DATY is off the menu until after removal of the female condom. I prefer my DATY prior to using the condom.
So, I don't see much difference in interrupting the session to put on the male condom or insert the female condom. The only difference may be that the lady still pays some attention to the male when she applies the male condom. I've had ladies put them on with their fingers, and a couple of times, the ladies put them on with their lips.
OTOH, it seems to me that the man might be totally ignored while the lady (carefully) inserted the female condom. However, a bareback sensation might more than make up for being ignored for that short period of time.
