i have experience with this because this for the past several years has been my addiction more than watching videos. sexual talking like this (over text im assuming) can be incredibly addicting. I was going to websites and chatting with gay dudes just because of how raunchy they are especially when trying to seduce a straight guy like myself. I was at the point were i was either doing that or going to websites of similar theme and just reading the comments and getting off to those.
In my opinion, all artificial sexual stimuli should be avoided. completely dissociate sexuality with screens, fantasies, texting, etc. anything that is not a real life person in front of you. Please take this seriously. I have serious problems because of this addiction and dont ever try to reason with yourself (because your addicted brain will once you get cravings) that "it's a real person on the other end so it is okay" or " this is just sexual text conversation it isnt pornography". Biggest mistake i ever made.
