It depends of your libido, your partner and orientation (asexual mostly don’t like it for example)
If you feel repulsed or disinterested at the idea of having sex, this might mean that it’s not for you
And of course sex in mangas is exaggerated
it depends a lot on what type of sex you're having and who you and ur partner are. it should feel good tho, that's important, but sometimes it can feel uncomfortable if you're not prepared enough, maybe even hurt (especially with anal, SPIT IS NOT ENOUGH!!! use lube!!!! no matter what gender u are!!). It's different for everyone tho, a good partner can sometimes be the most important factor, but some ppl just have bodies that have a harder time doing penetrative sex in general.
Does s*x actually feel good?
