You ask whether there’s an over-the-counter hormonal cream to restore vaginal elasticity. You’re finding intercourse painful and experiencing dryness.
Vaginal moisturizers will help to retain some moisture, but none of them will reverse the process—which is, medically speaking, atrophy given the loss of estrogen. The combination of moisturizers and lubricants will keep things comfortable for a while, but most women eventually need more.
Localized estrogen or the new pharmaceutical Osphena are effective; either requires a consultation with your health care provider. I’m not aware of any hormone-based medication available over the counter and, in fact, encourage a consideration of your medical history and current factors before use.
