The thing about gay couples having children, is that everyone of those kids where wanted, there are no accidents
The largest peer-reviewed study on the subject of LGBTQ parenting found there is no difference in the wellbeing of children raised in same-sex versus opposite-sex headed households. And in fact, some studies have found slight benefits in emotional stability and physical health for children raised in same-sex households!
Same-sex parents are more likely to adopt a child of a different race than straight couples. One reason for this is that LGBT individuals are also more likely to be involved in an interracial couple than heterosexual couples.
At the end, all that you need to have a family of your own is love!
