Sorry for bugging you guys..

But can someone proof read this paragraph.
Ohio Sen. Rob Portman is the first Republican senator to endorse same-sex marriage. Portman changed his views on same-sex marriage once he learned his son is .
" I want all my children, including my son to have the happiness in marriage that I have with my wife," Portman says.This shows that a personal experience can outweigh something that was once ideological. If Portman had stuck with his initial stance on same-sex marriage he would have had to tell his own son that he could not be married. But instead, Portman changed his mind and now wants his son to have equal opportunity to be married.

Thanks in advance

Great!

Sure! Here's the proofread version of your paragraph:

Ohio Sen. Rob Portman is the first Republican senator to endorse same-sex marriage. Portman's change of heart comes after learning that his son is . "I want all my children, including my son, to experience the happiness in marriage that I have with my wife," Portman states. This highlights the power of personal experiences in shaping one's perspective, even when it goes against their previously held beliefs. If Portman had maintained his initial stance on same-sex marriage, he would have been forced to deny his own son the opportunity to marry. However, Portman's change of mind demonstrates his belief in equal opportunity for his son to get married.

Please note that this is just a suggestion, and you can make any adjustments you find necessary.
