If my dh could not satisfy me sexually knowing myself I'd start getting fed up, trying to get him to change which is not a nice thing to do to a man and would hurt his ego.
Sooner or later I'd find other faults in the relationship and would probably look elsewhere, get sad and walk out. Yes, it means that much to me. I truly believe that a good love life and a sexual connection are what makes relationships tick. That's the point which breaks down first should something be amiss in a relationship or one of the partners feel tired, be ill, etc. It's optional, but oh so important. It's the intimacy of two bodies entwined and the minds opening up and trusting each other.
As said before: a hymen does not make a woman and from a medical point of view very few of us were physical virgins as a hymen can easily tear when doings sports. My first BF and I were both virgins and though it was special it was such an awkward fumble, neither of us having an idea how to enjoy one another's gift. I love the fact that my dh is fab in bed because he knows all the dirty little tricks and gets me going in every way possible. We've both had our share of partners and I'm glad about it.
It's only human nature to look beyond the rim of your plate and wonder what other sex partners might be like. I'd rather be with a man that's made his experiencesand knows the grass isn't greener than with one that's curious about other sex partners.
You may well say: 'Oh but he is totally content with me and wouldn't want for more.' Well, he's not gonna tell you, is he?
The one thing I wholeheartedly agree with is that it's good to wait a bit longer until one has sex. I had been together with my Bf for 4 years before we did it. The maturity and thoughtfulness you have when you're a bit older makes for a more satisfying and beautiful experience rather than rush into it at 12 years old because of peer pressure.
Whatever works for yourself is best. Don't let anyone take that away from you. I'd want my daughter to be careful about picking sexual partners and be educated about contraceptives and transmission of sexual diseases.
