How much does cellulite and stretch marks matter to guys?

I've been told I have a good body. I'm very tall and fairly slim, people say that I look like Maria Sharapova. I used to play sports very competitively in high school but once I stopped, I got stretch marks on my thighs and butt. I also have cellulite all over my thighs but its not that noticeable because I am pretty tan now. I am very insecure about this when I go to the beach and whatnot. Do guys pay close attention to this and get turned off by it?
