I’m a twenty eight year old heterosexual guy and have never managed to make a girl cum. I’ve had several different girlfriends and they all say they like what we do, but most often I cum and then they give up and we go to sleep or do something else. What am I doing wrong?

Statistically speaking, the greater number of clients you see regularly, the more often you'll have to intercept clients who clash with your own hygienic expectations. Here are my best client hygiene tips to set you – and your future clients – up for maximum success.

Recently we've begun to explore rougher sex with my husband in a more dominant role. I really enjoy getting aggressively penetrated from behind, but my husband has an exceptionally long dick and every time I have the desire to get pounded it feels like...

I've been dating the same woman since college. Our relationship is great and we live together full time, but we are not married. She still says "dating," or "my girlfriend," when talking about us. We also don’t have sex. Ever. Not even a little bit sometimes because it’s a holiday.

Is it possible to tell which sex workers like what they do for a living? I imagine that lots of them hate it and I wouldn't want to hire somebody who hated being with me. What are the signs that somebody enjoys their work and will like to be with me?

Am I still a virgin if it's just oral sex? I know all sex is sex, but if I've never had vaginal sex, aren't I still technically a virgin?

I'm in the middle of a fight with a sex regular via text message and everything each of us is saying seems to make it worse. I'm tempted to just block him and never answer any of his calls again, but I'm worried I might be misinterpreting his words.

I have been married to my partner for 9 years and he has begun to express an interest in opening our relationship. This really scares me because I don’t want to get any diseases or risk losing him to someone more exciting or adventurous than I have been. What can I do?

My first suggestion would be to schedule your sex date in advance. That way you can block off a lengthier period of time and ensure you and your partner won't feel rushed. This is especially important for women, as it typically takes us much longer to achieve orgasm than men.

Low libido isn't always a problem, although the pharmaceutical industry does its damndest to convince us otherwise. The fact is, sexual libido is on a spectrum that can fluctuate and evolve over time due to a number of both predictable and unforeseeable factors.

While it sounds like this is something you've thought long and hard about, many young women make an impulsive decision to jump headfirst into the sex industry and later regret it. Make sure you're interrogating your motivations. At the risk of sounding like everyone's mother, porn is indeed forever.

The thing about "normal" when it comes to sex, dear reader, is that it's an arbitrary concept. Research statistics on sexual partner numbers typically define sex narrowly – e.g. as penetration with a penis present – and therefore inauthentically.

You deserve all the sex toys and vibrators you want, dear reader. Your partner (hopefully!) brings more to the relationship table than sexual prowess. He's not responsible for your orgasm; only YOU are responsible for your orgasm.

Andre Says: I can in no way make predictions about the quality of another provider's services. What I CAN promise you, is that when it comes to booking a sex worker, there is typically a correlation between increased security protocol and the provider's legitimacy, experience and professionalism.

Andre Says: Unprotected anal sex is the riskiest kind of sex when it comes to STDs, because of how delicate the lining inside the anal cavity is. Should a disease or infection come in contact with even the most microscopic of tears, there’s a significant chance of it moving into the bloodstream.

Andre Says: If I were you, I would sit down with my partner and apologize. Apologize for making him feel pressured or invalidated by your skepticism around their allergies, and explain why you reacted that way.

Andre Says: You define the sex you are having with your boyfriend as "fine," which isn't exactly convincing me that you are getting your cakes satisfyingly smashed on the regular.

Andre Says: Here in the United States we’re still doing a shit job of preventing the transmission of sexually transmitted diseases and infections, a failure which can largely be chalked up to our obsession with shame.
