Condoms are pretty easy, durex mutual climax has numbing lube inside and ribbed outside to give the girl more pleasure. Ribbed also usually means a bit thicker.
I would also say don't worry too much about finishing too quick. Remember that she's not just there for your pleasure and once you're done, try to help her out with your hands. Don't feel scared to ask her to show you what she likes, it might be a bit awkward at first but it's the best way to learn.
Also, statistics are pretty high for women who never had orgasms even after years of having sex so not everyone can manage that. Only minority can actually finish just purely from penetration and even less can do so from playing with their breasts. Most will require clitoris stimulation.
But yeah, if people say they usually have sex for like 2 hours. They probably means some foreplay, round of actual sex, then probably some cuddling or soft foreplay for a bit until they're recovered, then actual sex again and so on. Recovery speed varies by guy tho, some can go again in like 5 minutes, others may need 30.
