My gf (age 43) recently broke up with me (age 38) (we were together just a few months), though I think we were actually more FWB's. She said her libido was on overdrive, and was inccessantly telling me she was horny. After the breakup, she said she wanted to stay friends - though things ended on a sour note, and we've been NC for ten days now. Toward the end of the relationship she said she mostly liked me for the sex. She said I'm "hot" and "addicting", which strikes me as flattery. Tonight I had the idea of offering to provide -- eh chem -- erotic services for her :p. I haven't felt close feelings for her over the last few days, and feel I'm mature enough to handle it. (I've had FWB-ish situations before.) Is this a reasonable proposition or is it insulting? Will it lead to Bad Things? I also doubt the neccessity (lol), since she's attractive, and [according to her] guys hit on her when she's out. This proposition sounds a little nutty to me, but I'm asking in earnest (it's 2018, right?). Please provide feedback.
