This is pretty common. Don't worry about it.
To get over being nervous, practice doing what you are nervous about. Just keep practicing sex, and stop thinking about sex. Just lie on top of her naked, talk for a while, caress her hair, kiss her neck, or just cuddle and rest naked. Don't expect your body to respond, and things will eventually happen naturally. Just go slow and relaxed.
Sometimes I feel more relaxed with her on top, and me on my back. Try that. Just talk and kiss and don't expect sex. But if it happens it happens.
And use come kind of lube if you need to. There's no reason why either of you should get chafed. Don't use any oils with condoms. If the condom is bothering you, try a thinner condom. List of condom thicknesses here: [url]http://redd.it/oupp3[/url]
