I was making this post as a reply but it's probably generally useful for anyone on the fence.

Circumcision is a moral crime. People who have circumcisions or have only interacted with circumcised penises probably do not really know how a normal penis actually works, or how intercourse is actually meant to work. With both types of penis the skin of the penis is anchored to the same points but a circumcision removes an extra three or so inches of skin (the foreskin is folded over itself so its length is twice what it appears). This means the skin of a natural penis can stay almost stationary in your partner for the full length of a thrust. This has multiple benefits, it is more stimulating for both participants because the skin exaggerates texture; it preserves natural lubrication because you are pulling three inches less skin into the open air with each thrust (this becomes more important with age); and it produces less friction which sounds bad but friction and stimulation are not the same thing so it extends sex and makes sex more comfortable for both partners without sacrificing stimulation (and if this seems unlikely consider it is essentially the same function lubrication serves and no one has ever complained about a vagina being too wet).

Circumcision is every bit as reprehensible as FGM and for the same reasons; the only difference is a matter of degrees.
