How can I introduce myself in English?

I usually prefer the following templates based on hints and personal introduction, famous PI

Please let me introduce myself first. I am an American English teacher and am currently an amateur blogger who lives overseas. I have shared political and social views closer to progressive people, but I have been influenced by the US Constitution, Individual Freedom, Free Market, and Negative Rights. I am very free to call myself a liberal now. You and I understand that the second amendment protects the inherent rights of all individuals with guns and opposes the legislative power of law and the physical strength of law enforcement. The second amendment was prepared to prevent tyranny and protect freedom. "It should not be infringed" is the conclusion that the need for armed militia to maintain "free national security" is an explanation. There is no doubt that this law means individual rights

First of all, I would like to talk about who I am. Please let me introduce myself. I am Japanese, four-year college, English major, especially English. Before entering university I wanted to learn Japanese, but I did not take the entrance exam of the university I want to enroll. As your information, I'm tired of becoming a college student. So here is the point. I want to share a story with you, that is, I fell in love with a girl and told her my feelings. I have not much experience in romance. Furthermore, I tend to fall in love with older women. Because they pay too much attention to me as if they would like to show me personal relationships. At the moment, the woman I fell in love is younger than me. She is even under 20 years of age! Those under the age of 20 are similar to tacit understanding, but alcohol drinking in Japan is prohibited by law.
