Maybe the following will help:
1) 7 inches is an inch-and-a-half above average
2) to have a chance with me, he'd have to agree to only put in 6 inches--IMHO, your husband too big & he's going to slam into my cervix if he thrusts that much in--ouch!
3) G spots are 1-2 inches into the vagina--big dicks, including your husband's 7-inch monstrosity
go way past them!
4) size matters, but in the opposite way that the male ego & porn industry seems to project onto us women...to make my case, I'll quote Betty Dodson, sexpert extraordinnaire, from her book _Orgasms for Two_:
"Far too many men are overly concerned with the size of their dicks instead of focusing on mastering sexual skills to become great lovers...according to the thousands of women I've talked with, most of them are more interested in what surrounds the penis--the whole man. Getting fucked by a giant, rock-hard cock that shoots a huge load of semen is a man's fantasy of male sexual prowess, not a woman's. While some experts claim a vagina is a collapsed space that will accommodate any size penis, I disagree. My own vaginal barrel is around 6 inches deep, so I have a problem if a man's penis is too big. Then I know it can hurt and I'm unable to relax and move freely. Small doesn't matter that much because even a finger inside my vagina feels good with the right rhythm and movement. Besides, like most women, I can't come from penis/vagina sex, so I'm more interested in what's happening to my clit..." (p. 169-170) ....yeah, what she said! Men, get over your penis size fetish, please!
