I'm a boy that just had his nails painted for the first time, thoughts?

i'm 16 and we were on holiday in cornwall in a caravan, and my dads girlfriend had some nail varnish and asked me if i wanted to have my nails painted, so i tried it and she painted my toenails and fingernails pink. i quite liked it but had it taken off the next morning. as well as thoughts, how can i get her or her 12 year old daughter to paint them again, and i can't ask directly as that would be too embaring :S thanks
