Is he only want me for sex?

Hi I'm Asian girl and my English is terrible but I really wanna ask u guys

We first met about a month ago, at the club
We started texting a week ago
And he told me that he was preparing an exam for being judge
last week we had date after dating he came to my house
I was virgin and I really wanted to keep this for my future true love so I blow him
And we had second date this week, he said to me he want to keep meeting me
We ate dinner and went pub
After dating he came to my house again and we had sex
But now he doesn't text me at all and not even calling me
My friends say all of his behavior were only for sex
I'm so confused because I can't figure out what his real mind
should I stop this kind of relationship or keep going?

Is he only want me for sex?
