Short answer
They are two doors into the same company. PositiveSingles, running since 2001, serves people with herpes, HPV, HIV, and other STIs and publishes its prices ($29.95 for one month at the website checkout on September 15, 2026). MPWH, running since 1999, is herpes-only, claims "2 million singles", and keeps its prices behind the login, where we could not read them. Both belong to the SuccessfulMatch network. Start with the one whose pool you can inspect free, which today is PositiveSingles.
Checked September 18, 2026 · Sources: PositiveSingles and MPWH, read first-hand, listed at the end · This site is run by an employee of the company that owns PositiveSingles. Why that matters
The short version
This is not a rivalry; it is a product line. If you want the larger claimed pool, published prices, and a free tier whose limits are documented, PositiveSingles is the testable choice. If you specifically want a room where everyone's condition is herpes and nothing else, MPWH is built as that room, but you would be joining without knowing what a subscription costs. When we compared them, every verifiable fact sat on the PositiveSingles side of the ledger, mostly because MPWH keeps its facts behind the door.
What they share
An owner, to start: MPWH's own page markup references SuccessfulMatch, the company behind PositiveSingles, and this site's operator is connected to that company, as the line under every heading says. That shared ownership has a practical edge to it. The network's current privacy policy, read September 18, 2026, says that your profile may appear on other platforms hosted by the Company, Affiliates, and/or Related Parties
. We did not test whether a PositiveSingles profile surfaces on MPWH or the reverse, but the terms you accept at either door are written for the whole building, and our lawsuit page covers why that clause has history behind it.
Side by side
| PositiveSingles | MPWH | |
|---|---|---|
| Running since | 2001 | 1999 |
| Conditions covered | Herpes, HPV, HIV, hepatitis, and other STIs, each with a profile label | HSV only: the living-with options are HSV-1 and HSV-2 |
| Member claim, as published | "2.8 Million+ Members" on the pricing page; "2+ million" in the site title | "2 million singles" on the landing page |
| Free to join | Yes; browse, wink, and reply without paying | Yes, per the landing page; free-tier limits not read |
| Paid prices | $29.95/month at the website checkout (September 15, 2026); $33.99 in the iOS app (September 17, 2026) | Behind the login; not readable when we looked |
| App-store ratings | iOS 4.3 of 5; Google Play 3.5 of 5 | Not read |
| Read on | September 15, 2026 (logged in) and September 17, 2026 | September 17, 2026 |
Member counts on both sides are the sites' own marketing claims, printed here with their source pages and dates, not audited numbers. Treat every headline count as a claim until a free search shows you active people near you.
Where PositiveSingles is stronger
The case is inspectability. You can read both of its price lists before paying, its FAQ documents what a free account can and cannot do, its profiles carry status labels beyond herpes, and its apps have public ratings (4.3 on iOS, 3.5 on Google Play, read September 17, 2026). The free tier is a working showroom: set your location, browse, and know what you would be paying for before you pay. The full picture, drawbacks included, is in the review and the cost page.
Where MPWH could fit
Some people with HSV prefer a pool that is only HSV: no explaining that your condition is not the one in someone's filter, no scanning labels. MPWH is built exactly that narrow, its landing page claims "2 million singles", and joining is free, so looking costs nothing but an email address. What we cannot tell you is what it costs to talk to anyone, because the prices sit behind the login, and honesty about that gap is the reason this page will not pretend to a full comparison. If you join and can read the pricing screen, that is the number this page is missing.
Which one to pick
Run the same test on either: create the free profile, set your real location and age band, and see who is active near you, because a smaller pool that is alive where you live beats a bigger one that is not. Do it on PositiveSingles first, since its free tier is documented and its prices are public, and add MPWH only if the herpes-only room matters to you. Whichever door you pick, the disclosure conversation is already handled on both, which is the entire point of this category of site.
How we compared them
We read MPWH's public pages without logging in on September 17, 2026: the landing claim, the sign-up options, and the markup that references SuccessfulMatch. Prices were not readable and are marked as such. PositiveSingles facts come from a logged-in read on September 15, 2026 and the public pricing page and store listings on September 17, 2026. We did not use either site's mobile apps for this comparison.
One more thing said plainly: PositiveSingles pays this site a commission when a reader subscribes through our links, and MPWH pays us nothing, so the recommendation above is worth interrogating. It survives because it rests on the one asymmetry anyone can verify in ten minutes: you can see PositiveSingles' prices and pool before paying, and you cannot see MPWH's.
