Is it normal to want to have sex with your cousin?

So I'm 24. My cousin and I have been really good friends for a long time since we're the same age and had a lot of the same friends. We have drifted apart some in the past couple years due to life, but we keep in touch and see eachother when we can. She is hot. I said it. I wonder what it would be like to have sex with her, and I really want too. Should I try asking her?
