Is this dildo a comfortable size for most or does it look like it might be a bit too big for the average user?
It would be too thick for me, but I don't think I could be used as reference for the average user. Even some 1" diameter toys are uncomfortably large for me. I wish that weren't so, because that toy looks very appealing.
From what I've seen, the majority of users are into toys around the 1 1/2" range in terms of girth, which about the average penis size.
what about if you were a virgin and you wanted to use it before you were with a guy?
I used plenty of toys before I was ever with a guy, some larger than this one. I don't know if I'd have picked it as my first dildo, but my confidence was below average when I started with toys. It doesn't look like a very large toy, so I think it would be okay for most people.
