I know you were all afraid Spectergirl forgot about you this week, but have no fear, I am here. Besides, today's question is 38 years old, I don't think another 24 hours is going to kill anyone.

Your mother needs to get laid. You didn't mention your father in your letter so I will have to assume that he is either not in the picture or just not up to the task.
Since you are writing for advice from a comic book I am going to again assume you're in your teens and since your letter was written in 1972 my time machine calculator tells me your mother is in her thirties. That means she is, in layman's terms, in the middle of her sexual peak. We in the biz know it as the "Why are your pants still on?" phase. And what a wild ride it is! I'll let you know how it turns out.
If you really care about this Steve keep him far away from your mother. If you also really care about your mother introduce her to Steve's brother.
