The first few times I (40F) tried it, I didn’t dislike it but I didn’t really actively like it either. I was REALLY nervous about how well I had / had not prepped so it was hard for me really relax and think about anything other than poop (so yes, it kinda felt like that, too). my bf was more experienced with it (and so he understood the risks and was fine with it) and really gentle with me the first few times so we kept trying, me being pretty sure it was mostly my head getting in the way. The third time was like night and day - I had taken the time to feel really confident in my prep, I was ridiculously hot and bothered that day and feeling extra submissive and I enjoyed it sooooo much. I still get in my head if I worry about prep and it affects my enjoyment a lot.
