Some kept their replies short and sweet (kind of): 

"When oral is not reciprocated... once or twice OK, but constantly is just annoying."

- Ashley, 23

"When the dude doesn't care about the girl finishing, or finishes in two seconds and calls it quits."

- Alexia, 24

"When a guy is going down on you and they try to make eye contact... I just don't like."

- Makenzie, 19

"When it takes like 10 minutes to stick it in because he can't stay hard."

- Lindsey, 20

"When he lets his dog stay in the room."

- Jenna, 19

"I hate when guys leave their bright lights on. I like to see what's going on but no one looks hot in florescent lighting." 

- Jenny, 27

"When he acts like he's amazing in bed but is actually terrible."

- Sophia, 23

"If he moans loudly while making out... I couldn't think of anything else the whole time."

- Danielle, 23

"I hate when my boyfriend puts his hands down there and accidentally touches my butt hole... literally the biggest turnoff."

- Louisa, 19

"I absolutely hate biting. I can't stand when a guy actually thinks it's OK to dig his teeth into my skin."

- Annie, 23

"When he can't stick it in and says its because you're too tight, like oh sorry dude, I guess it's my fault."

- Christina, 27

"When he doesn't cuddle for at least 5 minutes after hooking up."

- Nina, 25

"When guys skip foreplay completely."

- Blair, 25

"When he goes all jack hammer energizer bunny style and it's not fun for you."

- Natalie, 20

While other girls had more to say: 

"I hate when guys aren't comfortable enough to talk to you before to see what you actually like... I love a good choke and being dominated but some people don't, some want more kink, and some want more vanilla. You've got to figure it out first."

-Kateri, 21

"I hate when a guy gets frustrated that he can't make me orgasm during sex. They need to realize that a lot of girls can't climax that way so would they rather have us fake it instead of being honest?"

- Brianna, 23

"When guys are selfish in bed... it's a PRIVILEGE to hook up with us and they should act like it. They shouldn't stop when they are done, they should make sure their partner feels good too!" 

- Alison, 22

"Anything that just takes you out of the moment... like if you have nothing dirty to say then don't strain yourself trying to think of something." 

- Dani, 23

"When he gets too rough with you to the point where it's too much. I get it you want to act aggressive but there is no need for spanking and hair-pulling to the point where it's unbearable. Take it light at first and if you see I like it and want more, then take it to the next level."

- Hannah, 20

"If he calls you mommy and/or calls himself daddy during sex. It's fine if I say daddy first, but not if he initiates it. It's just weird and cringe-worthy."

- Chloe, 26
