The best way to learn English for single men

When I unexpectedly became a freelancer, life put me in the face of the fact that all my customers are English-speaking and will have to correspond with them, or else they can communicate in Skype with their voice. In all my life I have probably tried all possible methods of learning English.
1) I studied it at school and university (in fact, I got a bunch of wrong things that are not really related to the current English, which is difficult to unlearn).
2) Studied on courses Eshko.
3) Read all sorts of textbooks.
4) Read and crammed words from the dictionary.
5) I trained with phrasebooks.
6) I tried to communicate with native speakers in ICQ, Skype and more.
7) I went to a Protestant church in which there were free lessons with native speakers, and then a sermon.
8) I suffered from lingvaleo and analogues.
9) Chisels words with cards.
10) I tried to read books in English.
11) Probably some other methods that I don’t remember, who knows, write in the comments.

The problem of all the methods is their boringness, against the background of not much need for English, it is extremely difficult to learn it, I want to do anything but not teach it. The most fun was visiting the Protestant church (this place is respected), they had fun activities and on Saturdays we drove football to the field. Everything else loosened my nerves more than it helped me learn English.

The best way to learn English, which never bothers it is to watch porno casings with English subtitles.

Consider the advantages of this method:
')
1) You will learn such wonderful words as tight - narrow, knees - knees, elbows - elbows and many others.
2) The first 15 minutes of castings usually speak on all sorts of topics, from cars and work to movies and leisure. That is, your outlook in English will be very broad.
3) It's damn interesting what they are talking about, which makes climbing a dictionary or google translate not such a dull affair.
4) You learn not only to memorize words with the help of reading, but also to perceive English speech by ear (a very important element, I still cannot understand half of words with some customers by ear).
5) It is damn interesting and never annoying.
6) Supports male tone.
7) Combine business with pleasure.
