Yes, that’s always been my concern. However I’ve never had any issues when I’ve parted ways with an SB, but I want to keep it that way
As you’ll see in many other posts on this thread (If you have a week to wade through them all) the SB world isn’t really about saving money. Although I’ve had some great sex with SB’s that was on par with the best SP’s for far less $$, the leg work and effort is much higher. There is a “thrill of the chase” factor for me in pursuing SB's, but if you just want to get laid by a hot girl SP’s are definitely the way to go.
