not pursuing relationships because of body image issues?

I'm at the lower end of the healthy weight going by BMI standards (10st, 6'0) but of course that doesn't take into account body composition. I have a fair bit of fat on my stomach so I'm not comfortable with taking my shirt off which makes it difficult to be intimate with a partner. I've girls openly express interest in me but I've kind of just brushed em off and closed myself off assuming they wouldn't be attracted to me. Lets be honest physical attraction is the basis of almost every relationship. What can I do to overcome this problem? (besides going to the gym - I already do)
