Not true, you have to understand homosexuals are about 1-2% of the population. Heterosexuals are 98-99% of the population.
So, you may have more incidence of abuse by heterosexuals, however as a percentage of the heterosexual population fewer people are pedophiles. 1% of 99% is a much higher number than 1% of 1-2%. The reality is when you adjust for their representative percentages in the population, homosexual men are 44 more times likely to be a pedophile than heterosexual men.
It simliar to the welfare, more whites are on welfare than blacks, however as a percentage of their populations blacks are far more likely to be on welfare.
