How soon is it to take the next level in your relationship?

You sound very nervous honestly. Now relationships and even things that aren't relationships move like bullet trains these days. So do things on your own accord when you are prepared and most of all please be safe and plan for sex just in case you decide to change your mind. Also talk it out with your boyfriend let him know where you're at with this and vice versa keep the lines of communication open. Best wishes.

Just wait until you’re completely ready to be intimate and don’t feel pressured into doing anything - if you feel like it’s affecting your relationship then have a talk with your boyfriend explaining your concerns

Ok, so firstly your vagina being too tight... You cannot (sensibly) and should not do anything about this. secondly your hair worries... look, there are a number of ways to shed hair off of your body in today's day and age, and there is such thing as getting ready to have sex if it's someone you care about. I would say you start problem-solving if it's going to make you uncomfortable. If it makes you feel unattractive then do something about it. Finally, sex. If you feel comfortable with having sex with him, and you want it, and you're ready then go out and do it. He sounds like he's trying really hard to be a good guy. Also, keep in mind that the texting may have slowed down because there is less to talk about now... you have known each other for a few months, you cannot expect it to be like it was when you first met... So be confident, and go out there and do what you want!
