Boyfriend way more experienced

I've never had a sip of alcohol or done any drugs all my life. I've had had 3 sexual partners, including my current boyfriend, and with each one I struggled with the thought that it was wrong and I should've waited until marriage- making me feel guilty and shameful at times. My current boyfriend has had crazy party's giving him nicknames because of things like getting a blowjob while somebody else was in the room. He smokes were and drinks alcohol regularly. He use to smoke cigarettes but now he vapes. He's done acid and shrooms and a whole list of other things, I'm trying not to be judgemental but it makes me pretty uncomfortable when he tells me these stories
