My Boyfriend Gives Me Money Only After Rounds of S*x

If a guy doesn't trust a lady but needs her to be "curing" things for the time being, this can happen:

I sometimes spend the weekend at my boyfriend's place... but I suddenly began to realize that he grumbles whenever I visit him during my menstruation. He would reluctantly give me just N1,00 for transport. 

Another thing I observed is that he gives me money based on the rounds of s*x he has with me. Let's assume we had s*x 5 times, he would give me N5,000  for transport and on the day or weekend we have it only 3 times he would give me N3,000. 

I think my boyfriend is paying N1,000 for every round of s*x he had with me.
