I started trimming about 15 years ago - it got me a lot more BJs. About 10 years ago I just pulled out the razor and never turned back. It took my wife a little longer to go along - but once she discovered how more sensitive she was - and how much easier orgasms were, she also took up the razor. Since then she has had the laser treatments and is 100% smooth - 100% of the time.
I LOVE my husband shaved. Makes his cock look even bigger, and I love caressing his smooth pubic area. Myself, I prefer trimmed with a little triangle but I'm too lazy to keep up with it on a regular basis. Good thing my husband doesn't care.
