Best friend is mad at me because I opened my stupid mouth

I have a big mouth and don't always know when to to shut up and I pissed my best friend/ roommates off because I couldn't shut up. He got his first girlfriend. You want to know how old he is? 25. Never had a girlfriend, still a virgin. He is the oldest male virgin I have ever met and I've given him shit about it. Also about never having a girlfriend. She was over our apartment and I got to meet her. They have been going out a month now so I asked them if they had done it yet? She blushed and said no. I told her "You know he's a virgin, so if he isn't good the first time give him another chance". She looked awkward and he looked pissed at me. I decided to give them some privacy so I left to my room and told them "If you're gonna do it remember safety first ". Don't bother calling my obnoxious. I'm aware I'm obnoxious. I heard her leave like 5 minutes after that. I went to talk to him and told him "You missed your shot. Better finally lose it next time". He told me I'm the fucking worst sometimes and went to his room slamming his door. I see now maybe I was being a little obnoxious. I tried apologizing but he told me to not talk to him. Should I go out and buy him some "I'm sorry for talking to much" Candies?😅
