What gender you are shouldn't dominate your tastes in things. Just because you're a boy that doesn't mean you're not allowed to like dolls. Besides, in the end they're just representations of the human form anyway and people, whether male or female, like the looks of other people, don't they? I have a guy friend who loves my dolls and while he wouldn't want to spend so much on one he constantly makes me wanna buy another one. xD
Congrats on getting him! It's so exciting to finally get a hold of your doll after a long wait.
My two dolls keep me busy enough and I have other expensive hobbies as well, so I have to limit myself to two!^^' And yes, I think it's best if you spend your effort and money on your first one for a while. I think it's more fun if you have more clothes and stuff for him to wear than investing in another doll and both of them only having a few standard clothes.
