She made the call last Friday while addressing university students in Harare as the world marked 16 Days of Activism Against Gender-Based Violence (GBV).
Students and Youth Working on the Reproductive Health Action Team (SAYWHAT) hosted the event.
SAYWAHAT also invited academics, psychologists and researchers who tackled topical issues involving drug abuse, early child marriages and suicide among students.
Speaking to H-Metro, on the sidelines of the event, the former Studio 263 actress, called for stiffer penalties against men for sexually abusing young women and girls.
“As we mark 16 Days of Activism Against Gender-Based Violence, every man out there should know that we are not happy at all as mothers.
“We have the issues of nine-year olds in Tsholotsho and Bindura being sexually abused with one of them giving birth.
“We are not happy with this level of child abuse. We are also in solidarity with the mothers of the victims and we want the law to take its course,” she said.
Mavetera said it was high time an example was set to warn would-be offenders.
“Men should think before they act and whoever is convicted of violating children’s rights should rot in jail.
“Surely, we can’t have a society where old men are violating young girls’ rights as is the case right now.
“We also want more laws to be added and every victim, who would have experienced this needs counselling and rehabilitation.
“Counselling and rehabilitation should be prioritised to help victims recover from the trauma,” she said.
She also advised young people against committing suicide, when they encounter problems in life.
“We have also noted with concern the rise in cases of suicide involving young people, especially university students.
“We urge them to desist from such tendencies.
“It has been very disheartening and we don’t want to see our brilliant students taking away their own lives.
“Students should never think of committing suicide as a solution, but they can always find other solutions in life.
“As students, let’s know that we have a great future ahead of us.”
The lawmaker also warned young women to move out of toxic relationships to save their lives from abusive partners.
“To the young people in violent relationships, we simply urge them to make the right decisions while it is still early.
“There is no need to make a sacrifice when one is in a toxic relationship where they are physically abused.
“The best advice I can give them is to move out of those relationships and start afresh.”
