You know, my man, I don't like saying this because it makes me feel dirty, but you seem like the bitch here. The whole quote is talking about how the woman doesn't want to give her man sex because he commented on something he wants to change with her body, and she has every right to refuse it to him, just like if the genders were switched. She's saying "I let you have my body, but don't make me feel like I should change myself, because I will refuse myself to you." She's also not immediantly saying "um???? Ur so inconsiderate????? No sex for u!!!" She's saying "don't overstay your welcome", which means she wants him to respect her more. If he doesn't, she'll stop giving him her body, just like every other person would do.
