Okay, I am 5'2", 26 yr old, and weigh 114lbs...but I have had three kids(all boys) and?

I have stretch marks. They aren't as noticeable since I've been tanning but I feel gross. I want to wear a bikini(a normal, non-skimpy one) but I don't want anyone focusing on my stretch marks, but they aren't going anywhere. What would you do??
