Is my mom so desperate for male attention she's putting her daughter at risk?

My mother has been single for years now, and has been meeting new men, whenever she can. I have no issue with that. She's her own person, so it's up to her what she does. Nor does she require my permission or approval of her actions. What does bother me, though, is when these creeps (and yes, that is an appropriate term for these particular men) ask about me. They are happy enough to talk to her about whatever, but when they inquire about her family situation, and she mentions her children, the conversation shifts.

She tells them about me and my brother, and then the questions start pouring in. "How old is your daughter?" Never any questions about my brother. "Does she live there with you?" "Tell me about her?" "What are her interests?", etc. If I happen to be in the house when they call to talk to her, they ask to speak to me. My mother has even shoved her phone in my face in the past, just to accommodate these weirdos. One guy asked if he came to the house, did she think I'd be willing to get in his car with him and go for a ride?! Like, what the actual hell is that?! These guys are in their 40s, 50s, and even older. Another guy asked about my bra size, to which my mother just laughed it off and paid it no mind??? Why the hell would you not IMMEDIATELY shut the conversation down after hearing that? That same guy called her again a few weeks later, and started asking if I have a boyfriend and other EXTREMELY inappropriate questions.

I don't know if she's just so desperate for their attention that she's willing to ignore such disgusting behavior from these men, but it makes me feel extremely unsafe. She tells these guys where we live and everything. What if one of them comes to the house and takes things way further than just asking his repulsive questions? This isn't right to me. If I had a child, I would sacrifice anything to keep them safe. My mother is more than happy to entertain these weirdos, and it scares me so, so much. 

What do you thing is wrong with my mom? What should I do/tell her?
