Why does it hurt so much?

[liv198288]

Like really sore bum and thighs only after like 5 mins of riding. I am wearing normal primark cycling shorts as well but not seem to be doing the trick. And not to mention the awful wedgies.

No gain without pain is what they sometimes say, but just easy off a bit, go easy.
But be assured cycling is great for you, so don't give up.
Also, look into getting a female specific saddle for your comfort, ask at the bike shop, it matters depending on the size of you..ahem, rear 😊

I find the thin saddles hurt like buggery the first few times I start cycling again and after 4 or 5 times I’ve broken the pain barrier and it’s weirdly really comfortable but it’s quite painful until then!
I don’t use gel seat covers or padded shorts or anything, just put up with what feels like internal bruising for a bit and it all comes good. Until I take a break from it of course…

With padded shorts you shouldn’t wear underwear. You can use a barrier cream to protect your bits, and don’t shave/ wax off your pubic hair underneath as it really helps protect you. After a ride shower and apply Sudocrem or similar, and keep hydrated as it stings when you pee if you don’t. Once you are fitter and have better core strength you will naturally lift your bum off the saddle more and it will get less bruised, but it takes time. There are lots of people trying to sell you fancy saddles and gel covers but as long as the saddle fits your geometry reasonably well anything will do. I like a firm Brooks saddle, tilted slightly down at the front, and have been using it for 15 years. It gets better with age!

Another vote for thin, narrow saddle. Save the padding for your shorts.
Commando only, but if you are really not comfortable with the image, wear a looser pair over the top.
And get a proper bike fit, even if it is 'just' for casual rides. The difference that a cm or two in seat height can make to comfort is amazing.
