I tore my ex's fourchette during the first night of our honeymoon in Mexico. We found some Campho Phenique in the hotel's pharmacy and used it in conjunction with lube. Not only did it work on the wound, it has a numbing agent so the tear went pain free the rest of our romps. So did my dick, which made me last much longer than usual.
Prior to that week, we had torn it a few times, with a long hiatus in between fucking to let it heal. Because we were on our honeymoon, and we had a definite fuckfest agenda, pausing wasn't an option.
After that week though, the tearing stopped. Partially because her fourchette may have been properly stretched, partly because she stopped wanting to have sex... with me.
But that's another story,
