Why do people willingly do things that make themselves less attractive to others when trying to look for a date?

Hi everyone. I'm hoping to gain some insight about a guy I've been chatting with on a dating app. The guy admits he has a certain hobby that makes him less attractive to women, yet he will continue this hobby of his regardless of what others say. So it makes me wonder why he's putting himself on a dating app when he already knows that he won't be very appealing. 🤔
