I need some advice about having sex please...

Lyric
I'm 17 by the way and will be turning 18 this year. I'm not going to have sex for a long while, trust me, but I often wonder about it. It makes me a little scared sometimes because, not to sound vulgar or boastful, but I'm really tight- I mean I'm a virgin and I've never had mor than one finger inside of me. I also have a pretty low pain tolerance. I've tried fitting two fingers in there and if I take my time and go really slow, I can fit them both in. I know that most likely a penis will be bigger than my two fingers... I guess I'm just asking for first time experiences or advice on what to do when I do it (which likely won't be for another couple years or more) or tips from people like me who have done it (people like me meaning people who prior to doing it the first time were tight and couldn't fit much in there or whatever) I guess. Encouragement maybe? Idk. I have anxiety and I worry a lot but I just wonder about this sometimes.
