Tearing was, by far easier than the episiotomy I had. That was awful! The tear was quite small compared.
Your doctor / midwife can talk to you about techniques to use - like pushing slowly when the head/shoulders are coming out. Using mineral oil as a perinatal massage. I don't think this works leading up to birth, use it during birth. However, I could be wrong on the leading up to birth part.
By the time you are that far, you won't care - that is the truth. You will have been through approximately 40 weeks of weight gain, puking, breast tenderness, heartburn, stomach upset, constipation, constant peeing, irritable hormones, crying hormones, weight gain, greasy skin - or dry skin, greasy hair - or dry hair, stretch marks, shifts in balance, no sleep, restless leg syndrome and/or cramps in your legs, wiggly baby from the inside, too small of a bladder, etc, etc, etc.
By the time you get to birth you are like, ".F.I.N.A.L.L.Y! Let's get this baby outta here!" ;)
