I feel like g strings for men were never really in fashion. My man wears boxer briefs because that's what he's most comfortable in. It's sexy to me.
In my experience underwear is to be worn for comfort - my personal preference being boxers. When it comes to going into action, they're straight off in one movement with my pants, as if they're a single item of clothing.
My wife wears G strings for clothes where she doesn't want the panty line showing, always has. However when that's not the case she wears victoria secret boy shorts and man are they sexy Guess it's a win win
I have g-strings and wear them on occasion depending on my dress, as not to show a panty line , or nothing at all. If I am wearing a long enough skirt, I may not wear anything. For me it has less to do about the type if underwear that I wear and more to do with what it is made of. I love lace butterflies, but I like them made f a soft material.
