The world needs more romantic saps, don't worry
Yes there does appear to be a shortage of decent Dom/mes, or decent guys for that matter, but fear not- it'll happen.
Probably when you least expect it- I always say to anyone I talk to who's having probs finding someone that it's sometimes better to find a person they can click with, rather than a Dom or sub.
My wife isn't my sub- but who cares? She's been the love of my life for many years.
Oh, & you're way too young to be giving up! Enjoy your freedom while you can.
