Genuinely curious 🧐 what other's think?🤔

Ok so there's this elderly lady more like in her mid 60's or something like that.. she happens to be a neighbor of mine .. I live in a apartment complex, anyways she is a very friendly woman but talks often about very sexually inappropriate random things imo.. for instance she talked about teaching her daughter how to suck **** and bluntly stated it to 3 of the male tenants my boyfriend included... She never told me this or any of the other women, she also stated to them that she randomly sucked a stranger's **** in the woods just because he asked her and she was only 13... She goes on to say she was a very promiscuous woman back in her "days" and that she's had random STDs she's passed onto her past 3 husbands... Laughed about it when she was telling me this... It made me feel uncomfortable tbh cause I see her as a mother figure so to speak since my mom and I aren't on talking terms... Wondering why she bluntly stated such personal sexual nature things to the males only? Doesn't that seem odd? My boyfriend said he and the other men were left feeling totally uncomfortable as well... So what does she get out of re telling her promiscuity days to the males? Is she insinuating anything or is she overly sex deprived of some sort, or is she just bluntly too comfortable with her sexuality but mainly with the men? Hmm 🤔 seems odd to me but seeking others opinions.
