I think I am actually tighter after two kids than I was before! And I was pretty tight before. Strong vaginal muscles also help labor to go quickly, my labor was only 3 1/2 hours for my first kid. This is especially amazing when you consider that none of the women in my family were able to have children vaginally.

Sex is much much better, too. I am much more likely to have multiple orgasms and ejaculate now.
