I most definitely wouldn't change it. I was lucky as I resisted the pressure and was 20 when I lost mine. My bf was mid 20s and experienced. I didn't rush and he knew I wasn't going to jump into bed with him and when I felt ready (had done some fairly intense kissing etc before) he arranged a short break in The Lakes. Was rather nice us both knowing we wanted to and he knew I was a virgin.
Lovely hotel, I thought we would be having an evening out and coming back but it actually happened before the evening.
The reality is his experience is what it made it so totally nice. I felt ready, and he took so much time touching, massaging and frankly when I was so turned on what his tongue did down below. He also gently showed me what to do as well. As a PP said, the feeling of reaching orgasm was just amazing.
Sadly we parted as he emigrated, but the fact we didn't fall out enhances my happy memories of losing my virginity to him. We do still have occasional contact but he is happily based in Australia as a doctor.
