My spouse and I have traveled throughout Europe in the last ten years and have not encountered any problems. (As lesbians in our 40s-50s we tend toward the invisible anyway.) We try and be mindful of where we are and might subconsciously adjust our behavior for smaller towns as opposed to cities, but really, it hasn't been an issue. Cities are always less provincial/conservative than small towns so I'd say just use your best judgement when you are in the countryside. We've been to London, Paris, Rome, Florence, Venice, Prague, Madrid and Barcelona as well as a handful of small communities near these cities and islands in the Western Med. (This year we are adding Oslo, Amsterdam and Stockholm to the list!) We have followed Rick's advice and have been polite and observant and tried not to stick out as Americans as a way of showing respect for the locals. We do learn a bit of the local language to at least exchange greetings and goodbyes (the one exception was Prague - but there were so many English speakers it wasn't an issue.) The worst things that have happened to us are coming across rude Americans and feeling like we have to apologize for them, and getting ripped off - once only - by a cab driver in Rome. After the first two days of our first trip we learned to spot a scam artist (it seems most of them are Roma, but I hate to buy into the stereotype.) During the first trip we had some trouble with our bank and I learned to carry phone numbers other than the "report stolen credit cards" number (they held a check after we thought it had been deposited and my account was overdrawn. I left Chase bank after that.) My spouse got a horrible toothache that resulted in needing a tooth extraction in Palma de Mallorca - and we had to pay for it with a credit card (500 Euros - much cheaper than in the US!) Some of the best choices we've made were purchasing Rick's books Europe 101: History and Art for the Traveler and Mona Winks: Self Guided Tours of Museums. Other than that I'd advise watching Rick's three part series on European Travel Skills. If they aren't all here on the website I think they may be on YouTube, or you can buy the DVD. We've also rented apartments on Air BnB from people who designate themselves as LGBT friendly, which has been a terrific help in understanding the local culture. Best wishes to you and happy travels!
