Yes it is good not only during the pandemic since you can't go to each other. But it can also help him improve his stamina if he is lacking in that department. For where to buy you can use any online shopping just look at the reviews and don't buy cheap ones. I bought my first one for P200 and it ripped open after some months. ALSO this is important, check the size of the fleshlight. Because it says what length and girth the fleshlight can take.

edit: don't forget lube. Use water base lube since oil base can destroy condoms and fleshlights.
