Is it normal be a hetro-sexual and having no relationship experience?

[Edwardo Piet]

If you have no desire then it's normal. What's normal for you doesn't apply to me, or anyone else. Just you. As long as nothing is keeping you from pursuing something you want, I'd say you're just fine and keep on truckin'

This.

'Normal' and 'common' don't mean the same thing. Asexuality isn't common, but it is normal. Heterosexuality and bisexuality are more common than homosexuality, but that doesn't make homosexuality less normal. There's another example.
