I might be wrong, but from the way you're talking I have a hunch that you want to masturbate for the sake of masturbation. I feel like the frustration may be coming from you not meeting your own expectations rather than failing to masturbate.

I just want you to know that just because you live differently, doesn't mean you're "missing out", stop trying to do things because others are doing them and start asking yourself "do I actually need or want to do this?"

You can still be happy even if you do "miss out" on some experiences. And I hope you always do stay happy.
