Sex life help

So recently my wife told me she swallowed someone’s Load from a guy on her first date , I’ve been with her for 8 years and she’s never done that for me because it taste nasty , and she also told me his tasted worse . I don’t want her to feel obligated to do it to me , but how would you guys feel in my situation because I feel rejected , and I feel like I’m too ugly or maybe it’s because I’m overthinking it .
