hi! my boyfriend and i are both trans men with little prior sexual experience. he has found that he likes to be penetrated with a dildo and after seeing how much he enjoys it i wanted him to try putting a finger in me. if he goes really slow it’s fine for an inch or two but then it suddenly stings. he’s never needed lube and i figured i wouldn’t either because i get very wet but could that be the issue? is there anything else i should try? thanks 🙂
