Have you tried dating someone who knows about SA? Who really, really understands what it's like? That way they'll know you're just scared and it's not that you don't want to make an effort.

Sure it is. It's just...really hard to find someone you're perfectly compatible with. But the best things in life are the hardest to obtain.
No one I ever knew had SA. I have never met a person in RL with SA. So unfortunately I don't see a point.
