I have this neighbor. Never met him, just seen him around. He seems pretty alpha to me. I would love to offer my service to him (not just sexually) but the thing is, I’m pretty sure he’s living with his gf. Worth it?

It’s always worth it to TRY. I would just try to loooong play it and be careful. If he’s living with a girlfriend, they might be still in that “lovey-dovey” phase that is hard to break through. Try offering to mow his lawn this summer or something like that. That kind of service might open his eyes and give you an opening.
