I have a friend who lives in Germany. I am in Spain. He is straight and has a girlfriend. He invited me to spend a week at his house in Berlin. It was a week of lots of beer and fun. When he was alone with me, he acts more spontaneously. So, he asked me if I'm absolutely straight or bisexual. I replied that he was "straight". On another occasion, he told me it was open-minded. Also, he likes to talk about oral sex when he's with me. We're all in our underwear just talking and drinking beers. But there has never been any breakthrough in terms of sex. The fact is that in December I will spend my holidays in England and he told me that he would spend a weekend with me. So when he went to say goodbye to me at the airport in Berlin, he said: Does it suck dick in the UK? I replied: maybe. I returned the question to him, so his answer was perhaps also. My question is: whether it's all about a true friendship or whether he has other sexual interests with me. After all, he's making a point of spending a weekend with me in England.
