... maybe it was his own post?? So excited to finally get laid that he has to post it everywhere he can ..?
@Kaiyen (or the wider audience if you've gone): when you get a bit more experience, I sincerely hope you come to discover the joys of skillful sex (with a loving and fully engaged partner) as contrasted to the joy of losing-my-virginity hesitant and nervous sex.
Yes, as in everything, practice makes perfect ...
And yes, as non-PC as it is to say it, expanding your sexual experience with more than one partner (over a period of time) makes every encounter you have in future more and more rewarding ... You seem to still have a large dose of residual guilt about your sex drive, and I hope that goes away for you over time.
How you do it is your choice - relationship / hobby / FWB / player / etc. - and rest assured that your choice is never going to be right for everyone else
