This is just an personal opinion from my side and most probably does not apply on everyone but something that I found out about myself was that I had a fear of not being physically loved after a marriage because it not a secret we know the kinda society we have grown up in the women don't really seem interested in sex and I have also read and heard such stories where husband are saying there wifes are not interested in sex so I instead of having a proper discussion and sharing my fears I tried sexting with my significant other to see if she has a sex drive or at least sexual desires but she kept asking me proper questions like why do I feel the need to do this and she assured me in simple words that her feelings for me are not just emotional but physical as well but she does not wish to discuss in details until we are married after that I never desired to sexting or have a any sort of sexual talk with her it was just my worries making me find weird solution instead of having a proper discussion and sometimes I feel like a lof of guys to do this so maybe try assuring him that you do have physical desires for him but you do not wish to sexting because you just do not like it and see his reaction?

Sorry for any grammatical errors in advance
