The shoes that she has worn growing up have been too tight in the toe box, but the shape of her feet indicates that she is likely to enjoy sex very much - providing there are no social rules that attract serious objection from Religion or Policemen.
Are you the kind of man who believes she needs "all the sex her body craves", without you getting jealous if she takes lovers with horny big cocks?
Sometimes, some male friends of yours can befriend her by giving lovely compliments to make her feel "more desirable". This can lead to flirting and eventually sex with safe men she knows to help her start off her "adventures".
If she can see you are happy with her to have sex with your friends for "starters", she will eventually find handsome men of her own choice to spend quality time with.
She can't do this overnight, but she can ease into the cuckold lifestyle if she knows that you truly love her, and will protect her from the wrong type of man.
