I don’t really think you have to write an overtly sexual character to write a character who has a healthy sex life.
Emma Snyder on ATWT was certainly no sexpot, lol. She ran a farm where she worked her hands until calloused and had a gaggle of children. Still, the show didn’t shy away from showing her as a sexual being, especially in the first six years she was on the canvas.
Lucinda Walsh was a businesswoman who ran what was described as a Fortune 500 company. She was hard charging in the boardroom and the bedroom. She had many aspects to her character but she had needs and desires and made this clear. A few times, she almost teetered on the verge of desperation but not to the point where she was offering men her company to marry her, she was never that desperate.
To me, Eric was far from sensual yet we still saw him with a harem’s worth of women in his life. Had Bill Spencer stayed longer, I have no doubt he would have caught up to Eric, or come close. I just don’t understand why we couldn’t have gotten more attention to those aspects of the lives of the women who were supposedly in Bill and Eric’s age range, especially in those years where the show was supposed to be at its best.
