Just yesterday I was having a conversation with a friend about "hot" vacation get-away's with a lover. She told me one time she was in a remote destination in Mexico with a private beach outside her villa that she literally had sex on with her lover every day! She said they were basically more out of their clothes than in them, the entire trip! Wow!! Yeah, I think any place that's tropical, remote and perfectly warm and breezy automatically sparks up the hormones and naturally stimulates amorous feelings in people.
That said, however, I also find romantic ski vacations very romantic and arousing. There's something about snuggling all warm and cozy with someone in a log cabin with a roaring fire, while outside the snow blusters, that can make any level headed girl swoon and melt! Or what about big city destinations that have a nightlife pulse strong enough to palpitate any marathon runner's heart? Day trips to museums, lunch al fresco in quaint little bistros, evening dancing in remote plazas? ...Omigosh, now where did I put that passport application?
