I do not think that your poor communication skill in foreign language or ignorance about club culture has much to do with problem in sex life. Ten months is not a short time to start physical relationship. While indulging in sexual activity men hardly think about other things like your communication skills, language, hi-fi attitude etc. His turn on is more likely to be your look, your body and how you carry yourself. He might be suffering from some sexual inadequacies or misconception. Rather than playing around, discuss with him in a very plain manner. Do not blame him but talk about your desire to have the sex and try to figure out why he is keeping himself away.
