SPH prejac trigger

So, I (25M) have a small penis. Around 2” soft, 4” hard.

I have come to really enjoy SPH (small penis humiliation) and general humiliation about hit.

Lately I’ve been obsessed with lowering my ejaculation times and would love to have HFO or semi-hard HFO as well.

There are many times in my gym locker rooms, or when I go to a nude beach, or when I wear really tight speedos, that I see people laughing or snarking watching my small pp. This feels very humiliating and also exiting for me.

I have this fantasy that the only thing more embarrassing than being for instance in a nude beach and seeing a couple of girls or a hot guy laughing when seeing your small pp, would be to then while they are watching and laughing or smirking to the prematurely ejaculate during the situation in front of them without and hand use.

I currently do the timing thing with sph videos to get my times down, but haven’t managed HFO yet. Any suggestions?
