I don't think it's at all odd to have done more of this in your personal life than while punting. I've found the same. It's something that a lot of women enjoy with a trusted partner who they know is going to take it easy, but not many would submit to with a complete stranger, particularly after they've already had their pussy pounded for several hours earlier that day. It's in the same category as fingering in that regard. There's not many wives/gfs who would turn down a bit of foreplay before sex, but a large proportion of wg's specifically rule it out.
