Pluto in harsh aspect to Saturn is one aspect that could indicate sexual abuse.
It is not however a guarantee that it would occur.
You have Saturn opposing pluto, and they seem to be on the axis of the 2nd house and 8th house, self value and sexual matters.
The chart you posted is difficult to read, so if the 2nd/8th are not where it looks that they are, apologies.
You also have sun square mars, another difficult aspect, but the tight sun/pluto trine is protective and gives the energy and power needed to overcome.
