Is it sad that my first kiss was a birthday present?

All the way back in 2016 I had my first kiss with a female friend, who knew I was getting a little desperate. A few days before my 16th birthday she told me her plan so of course I was super happy, and when it happened it felt amazing. Looking back though I feel like it sounds kinda sad it happened that way, like without her being actually attracted to me and just doing it out of pity...
