Simple solution to that would be to fuck like 200 girls. Then your next LTR's got competition!

Why should it be an issue? It might bug you a little at first, but you have to forget about the past. It's irrelevant! The dude can't have been that good, or she wouldn't be with you now. It is that simple.

I don't think this would bother you, if you had slept with ALOT of girls. It's when you've fucked like 3 girls, you would prob feel intimidated.

Has it occured to you that it may also bother/intimidate the girl, knowing you've fucked loads of girls, or done stuff she hasn't, etc etc?
