There's no specific count of boyfriends you need to have had at any point of time in your life.
What's more important is that you find the person you're genuinely content with physically and emotionally.
Some Girls/Guys only have a long list of ex lovers because they tried so many times to find "the one" but failed to do so.
In my honest opinion, it's better to actually find someone you are truly in love with, than have a long history of breakups. Then again, it's also good to learn from past mistakes.
