Riding - and decreased sensation during sex (?)

[BlessedB]

Hi ladies,
This is embarrassing, but here goes...
I'm 55yo, post-hysterectomy in 2007, have been riding since about July, and purchased a road bike in the past month (Trek Domane - beautiful). The saddle is Bontrager Affinity WSD, recommended by a girlfriend. After riding I have some soreness in my sit bones and a little dull discomfort in the nether regions, but no numbness or pain-pain there. I've also started dating a lovely man in the past couple of months, and spent the night with him this past weekend. All good so far.

But what I noticed was, I didn't feel as responsive as usual - a sort of dullness of sensation in my lady bits, and an orgasm was a long time coming. Fortunately no pain. I would chalk it up to just lack of practice, except for the dullness of sensation, and am wondering if it could be related to riding, and/or my saddle. Has anyone else experienced this? Thank you for your thoughts.
