If a guy claims he never loved a girl and that he never had sex with her, is it true?
They’ve been together on and off for 6 years. She had the tendency to date multiple guys even early into their relationship. They stayed together because she kept coming back to him and he couldn’t find anyone better before he met me.
Well it comes down to the idea of trust. You need to ask yourself "Do I trust him?" If he truly loves you then he wouldn't have anything to hide and so he'd probably tell you if he was a virgin or not. He should feel that he can tell you anything, so if you know that he feels this way then you've got nothing to worry about. As long as you can make him happy, in time he'll forget about that other girl and that will stay as the past.
