Jmo, but it is possible she is working through the shame of her past actions...and she doesn't want the same type of relationship with you that she had with the men in her past.
If she is doing her best to change that kind of dangerous behavior, try and understand that she wants something better with you...and from you--Respect.

Because she is not willing to "put out" for you does not mean she cares less for you. In fact, it can be that she cares more for you.
Judging your relationship based on her past actions with other men will only hurt both of you.

Have you talked about this with her? Listened, really listened to what she has said to you? And expected the same thing from her?

Being blunt, but I do not think she is losing her high sex drive. I do believe she is no longer looking for love by having sex with men...
Loving you may be the best thing that has happened to her, and maybe she wants and needs mutual respect and dignity from your relationship.
A very healthy way to start one, jmo.

Best wishes for this to be sorted out,
Catherine
