It is likely that your gynecologist gave you hormone injections, possibly testosterone. There has been some scientific literature that says that Hormone Replacement Therapy (HRT) with estrogen may be given even in old age for sexual problems. However, the experts at this stage recommend HRT only for problems such as vaginal dryness etc. Many seniors enjoy active sexual life and indeed it is their right to do so. However, there is a shift in that they may now derive more satisfaction from cuddling, touching and kissing. This may be happening to you. Continue to enjoy foreplay which will help in getting that feeling. There is robust evidence that Testosterone therapy helps in sexual arousal in older women. Testosterone is available as cream and transdermal patch. You may discuss the use, side effects (virilizing effect such as acne, male pattern hair growth) and safety with your doctor. Hope this answers your question.
