You probably need a different saddle, but a bike fit might be cheaper in the long run! you can rule out the saddle quickly, better than trying 50 saddles and never getting it right, get the fit right and then if they tell you the bike is fitting you perfectly and you still hurt it's the saddle.
Do not tolerate labial pain. that part of your body is not supposed to get "calloused" or "used to" bearing weight like that.
it is not acceptable. really.
