What should one 'offer' in dating or a relationship?

The notion of having something to offer is why I never date. I feel I have very little to offer. I might be able to provide kindness and patience and I'm a good listener, but it seems people want excitement deep down. I really don't offer that. I have a moderate anxiety disorder so I don't go traveling, or do a lot of social activities. I fear a guy will want someone who DOES offer that.

What do you feel one could 'offer' in dating that is a positive aspect of a relationship? What do you enjoy most in a relationship?
