Worryinggg

Im always worried that I dont talk to or interact enough with my boyfriends parents. And im worried that they think I go to his house only to have sex with him so I must not care about them or something. It honestly weirds me out that when I come over, they probably know its for sex and ughhhhhhh wtfff. Also, I asked my boyfriend if he had sex with his ex every time she was at his house and he said no, not always but with me, whenever I go to his house we always have sex!! What does this mean??????
