Is it normal to think relationships are too much effort.

Hi, I just turned 19. I'm a virgin in a university renowned for having lots of willing lovers. I think I'm not bad looking and I think I can "charm" girls if I wanted to. I haven't been in a proper relationship ever. When I speak to potential romantic interests I think of all the effort a relationship is and kind of shut off my friendliness which results in me coming off as a snob. I don't have a sexual drive to find a mate and masturbation satisfies me enough to move on. When I'm not interacting with people I do get lonely but it's not enough to go looking for a girl. I have tried really hard a few time to have a relationship but I get bored with people really fast and the reward is just not worth the effort. So in conclusion I'm lazy,frigid, and I get bored fast. Is this normal?
