thsi came up today in a discussion with a friend, what is the smalelst size that you think could use a magnum xl without it like sliding off....or what i should say, is that whats the ideal size ? on another note, my gf and i have used regular condoms, but i notice that they seem to cause some pain. i dont know if its from loss of circulation or anything, but the condom seems very taught stretched out, and it doesnt go all the way to the base. is that how condoms should be? or should there be extra room.
