My husband said I’m STIFF in everything I DO!!!!! help me I need advice

Ok so right now my husband and I were just talking about massages and idk how our convo jumped to us not doing exercise and well I started telling him that when I was about 7yrs old I was a cheerleader till I was like 11 and that I was able to do the split and I was very flexible so then I get up the bed to c how far I can go to do the split and obviously I wasn’t able to go that far down so then he tells me “it’s cuz ur too stiff” and I kinda felt hurt when I asked him what did he mean he response was “ur just too stiff in everything” and I asked him to give me an example on what things am I stiff in and he couldn’t answer my question and then he just told me like when we horseplay, first of all let me tell u we don’t really play it’s rear when we do so I kinda took it to the heart and felt like he told me that I was stiff in bed like when we have sex 😢 I felt so bad and hurt I started crying I just feel like I’m not good enough for him my self esteem is really low right now I feel ugly and fat idk 😐

What do u ladies think I’m I over exaggerating or what do u all think he meant, oh and let me tell u well we argued cuz I told him that I knew what he meant so right now we’re mad at each other
