Ok, the OP Mr. Romeo was not the first date and it was appearing things were going along well as far as continuing the relationship, right up to the surprise part. It was the surprise that was a turn off. I would guess he felt encouraged to initiate sex. Apparently either Surprise! was not the right time or method for the OP to agree to intimacy. (Presumably they were not intimate before the surprise.)
I am not recalling any women claiming a similar surprise (could be wrong) but more of the (in my book) perverted stranger getting his rocks off by inappropriate sexual (of some sort) demonstrations inciting disgust or such.
In my experience working with a number of women, there were a large number with relatively limited acceptable sexual behaviors. Frankly I was dumbfounded at how limited, however none indicated they enjoyed sex period. The general run was frequent discussions of what they did not like about sex.
Could have been a regional thing, it was a church state after all. And I have not worked with a lot of women much in my years of employment so could also been a freak isolation.
Personally I do not have a problem with a naked surprise in general, as long as I am leaning to or currently in an intimate relationship. But as a warning to men, I think it could backfire, as it certainly did for Mr. Romeo.
My example: a fellow I was dating, not yet sure I wanted to be intimate with. I had a reason (Dr. appointment) to request if I could stay at his house to avoid paying for a hotel. He agreed and I expected to sleep on his couch or floor. He insisted I take his bed, eventually I was tired and wanted to sleep and gave in. Somewhere in the night he naked surprised me in his bed. The surprise was not the turn off per se. It was the inability to recognize no meant refusal.
I think it could be viewed I asked for the surprise. I asked to stay there, I accepted his bed, compared to the fellow laying the goods out on a table in a public place. In any case the surprise was a bad idea and pretty much took me off the fence then and there.
As for rude approaches...I am not a barfly, just never been my thing to go to a bar for a good time. (I think I am rather dull actually.) So once I was there in a bar, in my 30's and a very nice looking younger man approached and I was initially welcoming a conversation, flirting is fun. So is seeing the reaction when it is discovered I am older than I appear at first glance.
His first sentence was, "Do you want to f..k?"
I too blinked, and cocked my head wondering what this man actually said that sounded like do you want to...but really could not locate anything else it might have been.
"How often does that work?" I asked.
His entire demeanor changed, smiling elfishly and eyes twinkled, "Yes", he said, "quite surprising how well actually."
There were plenty of other potential aqusitions, and frankly younger and more appealing, the remainder of my stay but he stayed and entertained me the rest of the evening. Granted, this was years before the date rape drug, I doubt I would do so again. But I throughly enjoyed dancing and talking with this charming (and a gentleman) the remainder of the evening.
The thing about trolling is you never know what you will bring in.
