I don’t know, I don’t need any enlarging.

Only way you can enlarge what you have is with surgery. Pills and pumps does not work and can actually damage the organ. Be happy with what you have and technique is what works not size. The uterus is sensitive only on the outside and not inside. To large a tool can cause discomfort to most women. Use what you got and use it wisely. Laying sideways Butterfly and using fingers also to stimulate the clit will put her over the edge.
