Jon should get his cervix penetrated. Btw.
Yes irl it’s not technically possible, but lets all consider: 1) there are numerous entities in the universe of tma surely capable of getting their cocks (or tongues, or whatever else they have) inside of Jon’s womb, and 2) it would be Hot.
Also just fyi whether or not he would actually want anyone or anything fucking his womb is irrelevant to me. So.
