I know you can get some for the penis aswell to make it easier to last longer, but there are some around to reduce the feeling of the anus so a person can refrain from feeling as much pain.
and for the others couple of people saying about loose holes and negative effects, there shouldnt be either providing he is not stretching it too far, and by the sounds of it he only wants to stretch it a bit so he can take his BFs cock which wont cause any bad effects. As long as the muscle isnt overstreched it is able to retract to normal size.
