unremembered+lads

This shows the reader that this sonnet is not just some cliche story about "love". The speaker of this poem has not been a proper lady and has had many men in her bed. She enjoys it and the company that comes along with it. There have been so many that not all of them have provided a striking memory in her mind and heart. Yet, at least they were something to fill her time with. She will probably never see them again, these "unremembered lads."

This line also reaches back to line two, in which she has "forgotten." It is still not clear if this is purposeful or simply because there have been so many people in and out of her life.
