Relationships can be a minefield and each has its own trials and tribulations to work through.
But one woman's query about whether she should marry her boyfriend even though "the sex sucks" has raised a debate about what matters most in relationships.
Taking to the Reddit forum for a popular relationships podcast, the woman revealed she was worried about their sex life after learning he was planning to propose.
"I love my boyfriend but I just feel so confused," she revealed.
While the woman hadn't been with anyone apart from her boyfriend sexually, he'd had multiple partners.
She went on to explain she had suggested different means of "mixing it up" and her boyfriend had agreed to try and make things "less bland", including buying her a sex toy. But she still felt unsatisfied.
"We are about to be in a major life-changing decision together [now] the possibility of marriage is on the table," she pointed out.
"Is it bad to be worried about this? That this is what I'm going to experience for the rest of my life?"
She went on to add she felt like an "awful person for second-guessing everything based solely off our sex life".
Fellow Reddit users were quick to reassure her that she was far from "an awful person" - in fact, sexual compatibility is a key part of any relationship.
"[Sex] can (and does) make or break a relationship," one woman replied. "Compromise and communication are super important, and one of your boyfriend's goals in life should be to pleasure you! I would try to have a sit-down chat and explain your needs, wants and things you want to try.
"If he doesn't listen and try harder, then I would say definitely don't rush into marriage. You will be miserable. But at least you know this before you get into a marriage, so either you both work to fix it or you will be unsatisfied and probably eventually look for satisfaction elsewhere."
Another person added that it was more than okay "for sex to be an important factor - just like it's okay for it to not be one for others".
"But don't let it slide! Talk about it! The worst that can happen is you realise this isn't going to be a good situation and either way you can hopefully move forward."
"Listen to what your gut is telling you. Life is too damn short to have anything but amazing sex," someone else chipped in. "I married that guy. It lasted less than a year and a half. Now I am with the man of my dreams who absolutely knocks my socks off. Do not settle. Sex and attraction is important."
So should sex be the make or break of a relationship?
Certified sex therapist Laurie Mintz told The Healthy sex was the "glue and oil" of relationships, and say it definitely plays a major role.
Without it, she says, couples either fall apart or become roommates who share chores, worries, and an occasional laugh.
"In terms of the oil, sex helps prevent friction and makes you less irritable," she says. "I always joke with my clients who I'm trying to help get a better sex life that the things that irritate you about your partner before sex could even be endearing after sex."
It can also release all those feel-good hormones, including oxytocin and dopamine, which increases feelings of connection and intimacy.
According to research in the journal Social Psychological and Personality Science, you get all these feelings of emotional well-being and connections when you have sex once a week.
The key, adds clinical psychologist Megan Fleming, is to figure out what works for you in your relationship.
"If a couple isn't having sex frequently - whether it's once a month or once a year - and they're not distressed by it, then it isn't a problem," she says. "It becomes problematic if it's distressing to one and not to the other. Then it becomes a relationship issue."
