I need help

So i was messing with this one guy and there were times we’d have sex and he didn’t cum then told me it(my lady part) was too wide. Which I’d never heard before nor had any problems with anyone else before. Then months later I had sex with a different guy and I don’t think he finished either the second time we had sex so like am I the problem because it’s so embarrassing and literally makes me not want to have sex ever again. Like do I need to see a doctor?
