Depends who well you write the story and whether or not it has typical sex roles. If both partners are verse and there's plenty of sexual tension leading up to the sex, then it's worth it. Make sure that shit is also uncensored.
I feel like the first sex scene is the hardest one to write since there's a lot of expectations from all the previous sexual tension. Do you make them fuck like porn stars, do you make them both inexperienced, or do they just stick to foreplay? If you also put in too much sex , then you're basically just writing a porno and people will only care about fapping than reading.
