I'm a retired military, and I enjoy an erotic story with a story that includes plot and character development.
I also expect the author to know at least the basics of male and female anatomy. The average male cock size is 6.4 inches with a cir of 5.0 inches Well endowed males have a 7.1 inch cock and less than 1 in a 1000 have a 10" cock (if that many.)
The hymen is located at the entrance of the vagina it blocks entry, it's not located someplace inside.
If you doubt this, please send me an email and I'll refer you to reputable sites where you can read or see the data.
