I honestly think most people are with the wrong partner if they feel this lack of sexual desire for them that they need such a long time to turn on. Yes everyone's sexual response is different but it could be also that if you're with someone who you don't properly connect with emotionally, you're going to feel more inhibited around them.
Foreplay is designed to turn someone on, but shouldn't the majority of cases, the prospect of fucking your partner BE the turn-on? Like I get wet just thinking about him.
The problem actually is for me that I have a higher libido than him, it's not that he doesn't want to fuck as often as I do, but because of depression and circumstances, his body doesn't always respond the way he wants.
It's funny that society assumes it's always the woman who is less sexual than the man, I would say that I am more sexual than a lot of men.
But I'm also demisexual so unless I have a connection with my partner, my lust is undirected, more fantasy-based. When I am in love, oh boy. ;)
