Sure, if you’re worried that said person has had better experiences with other people and believe that spmeone’s peak sexual experience overrides any sort of romantic notions and other compatabikity. Frankly though, while that won’t actually be a problem if you’re at least vaguely competent at sex the whining about it and self-sabotage certainly will be.

Just imagine you yourself having several partners and other experiences. Would you want someone looking at you like “eww gross”? No, you wouldn’t, because you know that that’s not a huge deal. And if you can’t extend that courtesy to someone else there is no reason you should be anywhere near an intimate relationship until you figure it out.
