Intimacy with new boyfriend

I just started going out with this guy I met at work. We have been going out for a couple weeks now and I decided to have him over for a little home cooked meal last night. Anyway   after dinner we were watching a movie and he started getting frisky. He started to slip his fingers into the waistband of my jeans. I immediately shut it down and stop him. I'm really embarrassed because I have my ex boyfriend's name tattooed on my lower stomach. I was embarrassed that he would see it and it would be a complete turnoff. What should I do? This tattoo is ruining my life!!!
