Answering the OP's question, to be honest and after a bit of soul searching, no mate, punting has never affected my relationships. In fact the opposite is true, my personal sex life has impacted on my punting significantly.
No WL has ever made me want to end my relationship for her. On the other hand, I've started relationships with GFs that have made me completely forget about punting for a long period of time. Looking back, I've missed a lot of gems because of that. J Diana from Ginza was one example. At that time I was in bliss fucking my 23yo GF BBFS CIP so maybe it wasn't such a loss, but from a pure punting perspective it was a loss. Still can't believe I never had the pleasure of seeing that girl!
