Yes: Of course it is possible for you to have sex when you have urinary tract infection. I trust that you under treatment for the infection. Please note that trauma of sex may damage the lining of the urethra and worsen the infection and pain due to infection.
Best Answer: No, the L120 definitely does not have a detachable lens. Nikon's L series cameras are entry level compacts, and do not have any advanced features such as a detachable lens. In fact, none of Nikon's compact cameras have one. If you want a detachable lens, you need to get either a Nikon DSLR or their 1 series mirrorless cameras that will be available later this month. You are probably referring to a fisheye lens. Of course, you cannot use that kind of lens on a L120 as it cannot accept a different lens.
The lenses that have the built-in focusing motor have the designation AF-S, which stands for Auto Focus-Silent Wave Motor. Lenses that do not have this built-in motor cannot autofocus on the D3300 and D5300 camera bodies. Many, but not all, of the Nikon lenses have a switch on the camera barrel that allows you to switch between manual focus and autofocus. This switch is labeled with M/A and M. In the M/A mode, the camera tries to autofocus as long as the camera is set to autofocus.
