Sure, but you're making a lot of assumptions about what their relationship will be like beyond the sex. Like where you say he would be "doing all the emotional labor and other things to keep the relationship running smoothly" -- I'm not sure where you got that idea from. It is definitely not in OP's post. What if she does most of the emotional labor?

It seems like you're extrapolating from the sexual dynamic to an overall stereotype of a man who is a total doormat, which is not what I'm getting from her description of him or herself. Being sexually dominant in bed doesn't make you an abuser, being sexually passive doesn't make you weak.
