I lost mine at 18.
Was with a girl for about a year on and off, nearly lost it to her, but her sis was rushed to hospital, 10mins later and would have, week later we split up because of other reasons ... 4months later shes with someone else i find out she lost it to someone, i go out get really drunk and lost mine to a one night stand... can't remember girl or much tbh... big regret.
But few weeks later me and her get back to gether, no nervous first time stuff, and seeing how we tried new stuff with each other and found out what each other likes and just growing sexually wiht each other was to me a lot more rewarding. Were now split up.
I've had a new one nighters, and they don't compare to sex with someone that you know really well and know what they like and visa versa...
I've slept with virgins(3), and there is nothing fun tbh about it, they don't enjoy it generally as it hurts then.
My 2p.
