I think the last sentence should have read, AFTER not prior, yes if you masturbate there is what they call 'after ***' after the main lot comes out, ejaculate is the correct word. As far as cleaning up the mess, you can use a paper hand towel for the semen to shoot into, then put that into the trash bin as soon as you can. I admit when I was a teenager I masturbated frequently, just before I went to sleep and sometimes again in the morning before I got out of bed, then I just let it all come out onto the bedsheets, I don't know if my mom noticed any marks, but I imagine there might have been a few as I ejaculated a awful lot every time I did it.
If she did notice it she might have just thought, " O my son is a growing boy who does that naturally" and thought no more about it as once the sheets were in the washing machine that would get rid of any semen marks on the bedsheet or blankets. On the other hand there are mothers who would not take kindly to see all those semen marks on a bedsheet, in that case I would advise you as I have said above to get a paper towel and ejaculate into that and afterwards put it into a trash can.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
