Moved to a big city and can´t make new friends

So, I just moved to a new city - actually, it happened 8 months ago.

Things are fine, except for one thing: I don´t have friends! My only friend here is in a relationship and we aren´t seeing each other much.

I don´t bother going out alone - I never had problems with this, but the fact is: I can´t make friends and I don´t know what else to do.

I already tried in person and through Tnder, ####### and H[o]rnet - and in these places, apparently, people are desperate to have a boyfriend or they are desperate to have sex. Whenever I tell them I´m just looking for friends, they back off. It really piss me off.

In my profile I wrote that I´m new in town, looking for friends, but they always come to me looking for sex or for relationships (?!).

The city is big - 20 million in metro area -, so there are a lot of gay people, club, bar etc and there are a lot of new LGBT moving here everyday, but still, I can´t sort this out.

I´m really thinking about to accept any date even is just for sex to see If I can make friends with somebody, but I feel disgusted with myself, using people like this.

I realized that I lot of people have Instagram and they are popular and they at least have their connections in those social network and apparently is easy for them to make new friends [they, at least, show to have interesting lives and become popular], but I don´t like these things, especially Instagram which I think is a place full of low self esteem.

What am I doing wrong?
