Birth is painful. It's also beautiful and amazing, so if you want an epi so that you can enjoy the beauty of birth, go for it.
I had an epi with both kids, and my second birth was awesome. DD basically just slid out. I pushed once, then breathed through the contractions, and there she was. The doctor said that's common with second epi births, because mama knows what to do.
