It is normal to meet numerous strangers online for sex

Since I was about 16 I have been using gay hookup sites to have sex with other men. I used to keep my sexuality a secret and so I would use the sites as an outlet for my sexual desires. I would try to restrain my gay urges as long as I could and then when it became too much I would log online and find a cute guy and we would hook up and have oral sex and rarely anal sex. I have also participated in group sex but I still use protection (except for oral sex) and I get tested every 3-6 months for stds and HIV. Now I am 20 and came out of the closet to a lot of my friends but I still use gay sites to find hook-ups and I have honestly lost count of all the men I had sex with I dont even remember most of their names. is it normal
