wakenbaken, don't put too much pressure on yourselves to do it.
just have fun with each other, have a laugh, be comfortable being naked together.
Just try sitting about and chatting naked, and have fun.

Sex is uncomfortable sometimes!

There are times when my boyfriend can't get inside me, but it's just because you have to have a play around first, and relax.

reassure your girlfriend that you love her, and that what's the rush anyway? you have ages and ages to have sex, just take it slow, it'll get there.
