In Scene Five, why does Blanche say she wants Mitch

Blanche wants Mitch's respect.

Mitch--Mitch is coming at seven. I guess I am just feeling nervous about our relations.

[She begins to talk rapidly and breathlessly]

He hasn't gotten a thing but a goodnight kiss, that's all I have given him, Stella. I want his respect. And men don't want anything they get too easy. But on the other hand men lose interest quickly. Especially when the girl is over--thirty.
