<human>: I'd prefer female opinions. I'm 40 y/o male patient NOT looking for a relationship. A loner basically. 

I go for medical treatments three days a week. I'm one of the few younger patients at the center. The female staff (nurses and technicians) ALL say I'm attractive. They sometimes cluster around me. I reckon they do this because they think I'm shy and too quiet and are taking it upon themselves to help me out of my shell (as they see it). They're also under the impression I don't think I'm attractive. (I don't think I'm anything special, but I don't think I'm ugly.) Some are more outspoken with their flirting than others. Some are reserved but still convey that I'm "cute", "sexy", "the whole package", "silky smooth", whatever. One really gorgeous nurse volunteered it would be unprofessional if she told me what she wanted to do to me, so I told her to stop as that was sufficient a compliment, but she still went on to to emphatically say I'm "hot hot". (She's married.) 

I don't ask for the compliments. I generally seek to avoid the topic because I don't want to look like I'm fishing. It also makes me nervous and self-conscious. I don't talk much but I am polite. There was a time when they didn't compliment me, but now it's all the time. What is your impression of this phenomenon? What do you think the motivation is behind this behavior?

Summarize the given text in a few sentences.
<bot>: (???) Summary: Are they trying to improve my self-esteem (i.e., being "nice") like they seem to suggest, or are they actually flirting hard?
