How significant do you think this can be in a marriage? If both partners agree in blood writing lol j/k, that they will NEVER turn each other down for sex no matter the circumstance unless its extreme? I just hate when people say that their partner provides duty or pity sex or that someone always has to be in it before things can get going. Hence why there is foreplay? If its not being utilized you should start. Or you hear "well sometimes I do it when Im not into it". You're telling me you won't be into it after you start feeling all those sensations throughout your body and you climax? Granted you should climax, if you're not then you better start teaching your partner how to make you get there. I think the problem with a lot of couples is that priorities tend to get shifted. One might maintain the same or alter them around sex, the other may change them completely leaving sex on the to do list and not the priority list. Just trying to get some other perspectives and Id love for some satisfied spouses to chime in on what other incentives are good for keeping the sex life on track.
