I don't think you should hold a grudge towards him for what he did in a past relationship even if it was long term that relationship has nothing to do with yours and we all treat people differently , I completely understand why you'd be upset about him lying to you about being a virgin but maybe he didn't want to admit to you how he lost his because he's embarrassed of his actions in the past relationship and doesn't want you believing that's who he is a "cheater" now I can't tell you what to do everyone has their own set of boundaries and if he's crossed yours no one here should have the power to sway what you're comfortable with . However if you want it work I suggest you talk about in depth and how you feel...
