Birth control can change libido and smell, but it does not change attraction. The commonly cited study that freaks people out wasn’t a measure of attraction, just a tshirt smell test and it didn’t have a proper control. A small group of people on birth control liked the way a small group of men’s tshirts smelled better than a small group not on bc. As I’m sure you know, attraction is a lot more than just smell. If you’re into your bf, you’re into him.
