Ringstead Bay near Weymouth is a good beach, though quieter than Studland. It's around a 20 min walk from the car park (£5 all day) which also has a small café and clean toilets. I enjoy going here always find some fun there.
If you happen to be closer to the western part of Dorset, then try Ringstead Beach (just east of the Portland peninsula) - it's pebbly and a longish trek from the car park (walking shoes advisable!). Quieter than Studland, the eastern end of the beach is where you will find fellow naturists. Am planning a visit there soon ............ DeeDee, I would also be happy to act as your chaperone!

Have you tried Studland? If you are in Hampshire its just across the ferry from Bournemouth. Drive towards Swanage for half a mile and you will see cars parked both sides on the verges. Follow the path through the scrub and onto the dunes for about 15 minutes - gays to the left, others to the right. There are dunes that lead down to quite an extensive flat beach but beware that textiles walk through the area especially on the shoreline. Its a great beach, not been this year yet but had intended to. Generally, one is left alone but as afternoon turns to evening motorbike patrols have a habit of appearing lest anyone should be doing something they shouldn't! Oh, and the (male) meerkats wander around all day.
I love and miss the sound of the sea, the gulls, the slight breeze and warmth of the sun even amongst the dunes which can give shelter if the wind is strong - camping isnt allowed overnight but some small tents pop up on hot days as do wind breaks and parasols. There are no loos for a couple of miles or refreshment facilities so take everything you might need.
I would be very happy to join you - if you wish as I could really do with another sandy "fix".
