Sex isn't overrated, but it is more difficult than people think it is. It's very easy for many people, regardless of whether they are single or have been in a relationship for many years, to get complacent when it comes to sex. Even if you're having sex regularly, you can and should regularly be learning about your partner's pleasure as well as your own pleasure. What works, what doesn't. Again, most people think that as a process that means trying something new, but it really doesn't. It's much more nuanced than that and principally involves communication. It's not easy, but it makes a big difference. In your case, for example, you've lasted 8 minutes. Did your partner have an orgasm in that time? Assuming you're male and were having sex with a woman, they probably didn't. Did you enjoy it? Do you want to last longer than you did? Assuming you're relatively inexperienced, there are most certainly ways for you to last longer, probably enjoy it more, and give your partner a much better chance of an orgasm. It's just something you need to communicate about and work at.
