Went to gyno today

So i have a yeast infection tosay and went to the gyno to see what they say since i was given the one day pill. I'm 19 so my mom came and a virgin and never used tampons. They wanted to take a culture and i tried 3 times but just couldnt keep my legs open. The nurse seemed super annoyed but i just was uncomfortable. My question is after i have sex and all does this become more comfortable? I'm not into medical stuff and just want some advice. Has anyone had anything similiar? I was just super scared and ik  i was okay but i just wasnt ready to do that.
