Hi CircuitCore,
Having a foot fetish or being attracted to feet is actually quite common! Studies estimate 1 in 7 people are into feet to some degree. There’s nothing inherently weird or shameful about this preference.
The key is how you bring it up with a partner. Wait until you have some trust and intimacy established. Then let them know in a casual, confident way, e.g. “I think feet can be really sexy - is that something you might be open to exploring together?” Emphasize it’s just one thing you enjoy, not an all-consuming obsession.
Most open-minded partners will be understanding, even if it’s not their thing. The right person won’t judge you for this. Wishing you all the best in your dating adventures!
