Some people like to squeeze more lubricant into the sheath during use. No mess, no fuss. One can insert it directly into the anus perhaps over fingers, or you can put the condom over the penis and gently slide the condom in.

Women love the female condom.
Men love the female condom. Men say it's a nice change to have someone else get the condom on.
