How can I tighten my loose vagina?

I have given birth to three children. My last child was delivered without an episiotomy. I have noticed a change in the size of my vagina as a result of this. I am too embarrassed to have sex because I feel too loose. Is this common with multiple childbirths? I am too ashamed to ask anyone this. Please let me know if there is something that can be done to repair my womanhood.


Do I have bulimia and will it interfere with my birth control pills?

Once a day, after meals — whenever my roommate isn't around, I stick my fingers down my throat and throw up most of the food that I had just eaten. I do not binge — I only purge. I understand from my Psychology professor that the diagnosis of bulimia nervosa requires that the person binge and then purge. I am curious, then, what I have — do I have a form of anorexia nervosa or what? Also, I am on birth control pills and I am afraid that I might hurt their effect by throwing up. How long does it take for the pill to get absorbed into my system? I usually don't throw up until about 5 or six hours after I have taken the pill. Will this hurt the effect of the pill?
