Not always, some guys have genuinely insufferable sisters or even worse ugly sisters. I'm very lucky I got one so chill with a compatible temperament(and libido) to mine and fucking cute to boot. It also helps we're so close in age.

Not at all, I'm not short or ugly or have a micropenis, but I'm no chad. Honestly it just comes down to communication, with normal couples they both just expect the other one to somehow guess and figure it out and when he doesn't do it perfectly that's when the resentment starts.
Just talking it out makes stuff so much easier.

We must have been 13-14 when we went all the way, I remember by my 16th birthday we were already pretty comfortable with each other's body.
We're 31-32 now and our little princess is 5, soon to be 6.
