@A-happy-22-m Don't just come out with it in casual conversation, or in most first date scenarios (depending upon the kind of date and how much communication you've had before/what about). Just mention it at the same time you'd mention any other fact about attraction, when such a topic is fitting and natural. Treat it naturally and without embarrassment, same as you might mention you have "a thing for brunettes" or whatever.

@ROCCHA hi Roccha how's it going?

I'll be your friend
