Are you referring to some sort of "skislope"-philia where the physical slope itself turns the girl on?
Or, are you asking if going on a ski date is a turn on?
There's a BIG difference and you need to clarify this.
I like going skiing with a civvy girl but haven't gone to any compensated paid skidates although I did go to a few OTC.
What I write below applies to mostly civvie dates cuz I just don't see how it can matter during a paid date.
Cons 1: I don't like how it tends to "cover up" the girl's nice figure. Unless she's wearing yoga pants or something, those ski pants tend to look a tad goofy for both of us.
Cons 2: If she's not at the same skill level, it can drive you nuts unless you're patient. I like to ski on the fast side and girls are usually less risk taking and less into speed. If it's a date, I find myself skiiing with the girl on beginner slopes, intermediate slopes. My first relationship that lasted longer than 3 years, the girl was an absolute beginner and we were usually on the bunny slopes. ROFL. It's all good though.
Pros 1: You get to really talk about a lot of things together on the way up while you're sitting together in the lift. Fireside chat over hot cocoa is romantic. I think I usually scored on a ski date cuz it mixes things up with physical excitement, adventure, and then a cool down mode where you get to chat quietly and relaxing all lone, while floating several tens of ft above ground. The constant change keeps things exciting.
Pros 2: If your skill level is much better than her, it kinda gives a guy a chance to show the girl a little bit more about himself: most importantly his patience, ability to guide her along the way, and being the trusted guy who's always there for her when she wipes out on her ass.
If she's really good or much better than you, well your shit out of luck in that department mentioned above. lol If a girl is good though, then she probably knows it and you get to see her nurturing motherly side helping you get up when you wipe out on your ass. lo
