I bought a fleshlight for DH to use during my periods. Worked like a gem. Only advise from here, he would pull out at PONR – much easier to keep it cleaner that way. It got so that when I was not in the mood, I did enjoy watching him use/play with it. I got him the see through model – to make it more interesting for both to watch – don’t know if they still have that one or not? Good luck and enjoy
Once I tried a sleeve, it didn’t work as expected.
I think the sleeve was too small, or my shaft to wide for the sleeve; basically when I used it, it was too tight, it was blocking blood from getting into my shaft, so I was very flaccid. I think it has to be the right size, so that it allows blood to get into the shaft, but at the same time capable to trap some blood in it.
I had better results with improvised rubber bands and a few types of silicone penis-rings.
I tried the second one in this Amazon list, feels awesome, it makes you rock hard: https://www.amazon.co.uk/Cock-Rings-OXBALLS-Sex-Toys/s?rh=n%3A2758368031%2Cp_4%3AOXBALLS
