Who Are The Main Characters In 'Welcome To Sex'?

Mia, Jake, and Lena form this chaotic trio in 'Welcome to Sex' that’s impossible not to root for. Mia’s nervous energy is endearing, especially when she overthinks every text message. Jake’s earnestness—even when he’s being dumb—makes him hard to hate. Lena’s the wildcard, dropping truth bombs with a smirk. Their group chats in the novel had me laughing out loud; the banter feels so authentic. Smaller characters like Dev or Professor Carter don’t get as much screen time, but they leave an impression. It’s rare to find a story where every character, even the annoying ones, feels necessary.

Exploring 'Welcome to Sex' feels like peeling back layers of a very intimate, sometimes awkward, but always human story. The protagonist, Mia, is this wonderfully flawed college student who’s navigating her first serious relationship while grappling with societal expectations around sexuality. Her boyfriend, Jake, starts off as this charming but slightly clueless guy who grows a lot as they both stumble through misunderstandings and emotional landmines. Then there’s Lena, Mia’s best friend—a queer art student who’s unapologetically bold about her own journey, offering both support and tough love. The dynamics between these three are messy, real, and often hilarious, especially when Lena drags Mia to a sex-positive workshop that changes everything.

What really stands out is how the side characters add depth. There’s Professor Carter, Mia’s mentor, who’s this no-nonsense feminist with a dry wit, and then Jake’s roommate, Dev, who’s secretly crushing on Lena and provides some of the best comic relief. The story doesn’t shy away from showing how each character’s background shapes their views—Mia’s conservative upbringing, Jake’s 'nice guy' persona masking insecurity, Lena’s radical honesty as armor. It’s less about 'who' they are and more about how they collide, learn, and sometimes fail spectacularly. By the end, you feel like you’ve lived through their cringe, their triumphs, and their very relatable growth spurts.

Mia’s the heart of 'Welcome to Sex,' but honestly, the whole cast feels like people I’ve met in real life—just with way more dramatic timing. Jake’s arc from 'clueless boyfriend' to someone actually listening is satisfying, though I rolled my eyes at him hard in the early chapters. Lena steals every scene she’s in; her dialogue crackles with this energy that makes you wish she had her own spin-off. The author nails the way friendships shift when one person starts prioritizing a romantic relationship, and Mia’s guilt about neglecting Lena adds this undercurrent of tension.

What’s cool is how side characters aren’t just props. Dev’s unrequited crush could’ve been a joke, but his vulnerability when he confesses to Lena? Oof. Even smaller roles, like Mia’s judgmental dorm neighbor, feel purposeful—they’re the voices of societal pressure Mia’s trying to unlearn. The book’s strength is how it balances humor with weighty moments, like when Mia and Jake finally have that raw fight about consent and realize how little they’ve actually communicated. It’s messy in the best way.
