Ladies...Question about your births!

Charlie
Hi, I'm posting this here because I think it will reach the most applicable people. Im 5 weeks (super early!) but am thinking of the various birthing options. 
I would like to know if there are any women who are very small "down there" that were able to successfully give birth vaginally without any tearing or complications? I'm super small. Tampons hurt, sex hurts, and they have to use a child sized speculum on me at the OB. I'm terrified of having a tear (or an episiotomy that doesn't heal right) and having to deal with long term sexual and bowel issues. 
So of course the other option would be a csection, and I would like to hear experiences with that as well. Please don't sanctimommy me. I want to hear everyone's stories, and will ask all applicable questions when I have my first OB appointment. 
Thanks!! ❤️
