Solid Seman after long streak?

I just M'd (no P). I noticed that whenever I go a long time without M I develop little solid balls of seman. They are sometimes yellowish tint. But they are solid balls of goo.
This didn't happen when I was PMOing all the time. I'm not complaining I'm just curious as if anyone else has noticed this when they M after a long streak.

My theory is that the seman gets sorta compacted down there and usually before a Fapstronaut breaks his streak he fantasizes for a while and that stimulates the reproductive system and gets the seman ready. If one were to go several weeks w/o M then he would have heavy balls and it would be very sensitive. I've experienced this and it feels very good lol. But the point is that I think that seman gets buldged up down there and usually wet dreams clean it but not always. I think this is natural.

 

Snowball effect?
