Don't feel bad, my first time was not that long ago, and I am in my mid-20s. (Shameful, isn't it).

I don't have as much experience as other people here and mine don't seem to match others lol, but what I'll say is that I think it will be good whether you decide to do it alone or with a friend. I like doing things on my own too, and I hate the thought of how if I want to try it again, I'll have to find other people to do it with.. I can't just do it on my own, because I wouldn't want to bring this into my house (it's my parents' house, not my own). It's good that you won't have any others' judgements there to bug you.

However, I agree when they say if you're feeling anxious or something, it's good to have a friend there (someone who will calm you down, not play with your head). I think I would have felt a lot worse if I didn't have my friends there with me and to talk to if I needed their support or something.

Good luck, and can't wait to hear how it goes! As a new user myself, I wish I could experience it with you! hehe
