I have a hard time inserting anything over 7". I look for girth over length in a toy.

6-7 for me the only exception is my Jopen Intensity, but its not a thrusting toy.

Most of my toys are around 6-6 1/2 inches.

For insertable length, my longest is probably 7" - 8". I wouldn't be opposed to getting some that are longer. I'd rather have too much length and not take it all, then to have a toy that's not long enough for it to reach where I want it.

My wife's vagina (like many I'm sure) - is quite short to start out. In fact I can touch her cervix with my middle finger - and I have small hands - that's just 3.5".

But as she becomes more aroused, her vagina elongates and since I'm about 7" her body has learned to accommodate me - and any dildo that length. However we have a couple of longer dildos - and when highly aroused she can get to 8 or maybe 8.5 inches. She can take most - but not all of the Vixskin Outlaw - which is 9" long.

When we get into using the longer toys - I let her be the guide. I'll press forward being sure not to go too far - then as she is ready, she press against me letting me know to go a little deeper.

Soft toys like the Vixskin are quite a bit safer. If your using glass or metal - extreme caution has to be exercised.

7-8 anything bigger seems to hurt too much

I prefer about 6-7 inches. I got a toy for review and my first thought was I was glad no man of mine has ever been that big. lol

i would prefer something within the 6-8" range, but with many rabbit vibes the insertable is only 4-6", which is something that i am totally comfortable with too, and can often hit my g-spot.

Toys that are too long for me to use vaginally can be ok anally. Or I can just use the leftover length as a handle.

Around 7" is the longest I have, but I never insert it all the way.
