When you have sex for the first time, you don't actually feel like you lost anything. You still feel the same. At least women can break their hymen (if they haven't stabbed themselves with a dildo or gone horseback riding) when they first have sex. You should be able to at least shed something on your meatus lol. Virginity for men isn't as exalted as it is for women, yet we get ridiculed for it.
Anyways, your first time probably won't be your best, so just relax and enjoy yourself. Good luck.
