Tearing

Alright FTM here. EDD is tomorrow, and lost my mucus plug today. Baby will come when she is ready though.
Anywho, I'm very nervous about tearing a lot. Are my chances higher since I haven't had sex ONCE this entire pregnancy. Okay, maybe my SO and I were intimate about 3-4 times throughout these 9 months :'-( Yeah, talk about feeling attractive. Now I'm concerned about being torn front to back. Ugh. But, since I haven't had much "exercise" down there, other than some Kegals, doesn't that mean baby will have less room or ease of coming out? This is embarrassing, but I'm wondering if I should do any kind of "prep"? 
Has anyone had any experience with this correlation? I'm seriously starting to worry. 
Please give me some truthful words of advice. 💛😥
