Strange timing every time

Is it all at all possible for intercourse to somewhat benefit the timing of a period? Could it by any chance be the forceful penetration that triggers the bleeding I get shortly after having sex? Surely this cant just be spotting or even a small amount...

of blood due to intercourse and it does in fact last for the appropriate extent of a normal period. Whats going on?

It's Normal *^^
When you have sex it just helps your period along.It doesn't force it to start.
Any if it is just spotting it's from you upcoming or your last period.
It's perfectly normal though.
After sex you leek because during intercourse your pathway opens more
so blood will escape much easier.
