What fruit?

I am a picky eater, have been a picky eater all my life. I managed during my late teenage years and early twenties to acquire a taste for vegetables (and I am grateful that I did), but fruits (apple, grape, etc) are still a problem for me.

I have identified however, that I like

• Mango
• oranges
• lemons

Now I wonder what fruit I could "try" next. Preferably I would not start with Apples and Bananas (as a kid it was constantly suggested I should eat apple/bananas that I don't have the best memories in this regard, I think these will be tougher fruits to start with).

Why am I asking this? Ultimately I want to balance out my diet more and potentially get into a position where I can opt for fruit over chocolate if I want to have something sweet.
