Messy fwb situation and am I a virgin?!?

Basicallyyyy I dated this guy last year for about 5 months but we never did anything apart from make out because we were only 14/15 and I wasn’t ready but then we broke up on bad terms and didn’t talk for a while but about 6 moths ago we became friends again and we both knew there was always something between us, we always messages and flirted then in April so 2 months ago I suggested fwb and he was totally up for it. I wanted to lose my v and I felt the most comfortable with him because we were good friends and cared about each other. We had long convos about it and he was really nice about it all. I was still a virgin but he had been w two girls but only had sex 2 times (so once w each girl lol obvs) he came over when I had a free house and we chilled at first he then figured me and we made out we then started to get ready to have sex. He has a big dick lool so I was kinda scared as I knew it would hurt we were in missionary and he put it in (soz if tmi) after about 1 min he could see I was in a lot of pain so suggested we stop because he didn’t want to hurt me. We stopped and I’m not even sure if I would class my self as not a virgin because yes it went in but I couldn’t tell if it went the whole way plus it only lasted about a min so no one cumed. Then we j chilled I gave him a bj and he fingered me again. We talked a bit after over text and in person but it fizzled our as I neither of us ever had a free house. He then slept w another girl just once about a month ago. We talked again the other day and said we both wanted to try again. Basically what I’m saying is how do I go though it but then stop the pain if we try again and also I don’t really know what I’m doing so please can I have tips on how to be good during sex and for bjs. And is he the right guy because yes we care about each other and there’s a lot of sexual tension but he’s been w other people and I haven’t. Lastly would you count me as a Virgin still lol I wanna know
