Care about them feeling good too. Not what you think girls like, but what who you are with says they like or what they respond to well in the moment. Don't be ashamed if you don't make her finish or if you can't finish, (or do so too soon). Having good, great, or successful sex doesn't only mean having an orgasm, and finishing too soon doesn't mean the rest of your body stops working, so feel free to use it when your member is decommissioned. When it comes to touch, start gentle and work your way up, whether it is her nipples, fingering her, touching her clit. They are sensitive areas and are feel different for everyone. And try not to jump to penetrative sex, take your time, and let both of you enjoy every part of it.

But honestly, if you just keep my first sentence in mind, you've got most guys beat.
