It literally says in the quran you are allowed to have sex with the slaves you own.
If you're allowed to have sex with slaves, then i'm pretty sure you're allowed to have them.
Also, Islam is not a country, it's a religion. It is held at a completely different standard. Islam based on Quran and Sunna. Now nowhere in either does it abolish slavery. In fact, slavery is somewhat encouraged by saying there's nothing wrong with having sex with your slaves.
Also, you're not the only one. Don't feel bad.
