15 SEX PARTNER FOR 22 YRS OLD?

I had always planned to remain a vírgin till I got married.. I tried to stick to this plan but at the age of 22 I lost my vírginity and I absolutely loved it. Its 4 yrs later now and I have slept with more than 15 men. I'm currently in a relationship that I'm hoping would lead to marriage.
The other day my partner asked me how many men I'd been with before him and I said 5! I was too ashamed to say the real figure. Is 15 high? Whats average for a girl my age?
