   SUMMARY ORDER

Appellant Alex Mass, pro se, appeals the distinct court’s grant of the Defendants’ motion for summary judgment, dismissing a complaint alleging gender discrimination in violation of Title VII, the New York State Human Rights Law (“NYSHRL”), and the New York City Human Rights Law (“NYCHRL”). We assume the parties’ familiarity with the underlying facts, the procedural history of the case, and the issues on appeal.

We review orders granting summary judgment de novo and focus on whether the district court properly concluded that there was no genuine issue as to any material fact and the moving party was entitled to judgment as a matter of law. See Miller v. Wolpoff & Abramson, L.L.P., 321 F.3d 292, 300 (2d Cir.2003); Republic Nat’l Bank v. Delta Air Lines, 263 F.3d 42, 46 (2d Cir.2001); Allstate Ins. Co. v. Mazzola, 175 F.3d 255, 258 (2d Cir.1999). In determining whether there are genuine issues of material fact, we are “required to resolve all ambiguities and draw all permissible inferences in favor of the party against whom summary judgment is sought.” Terry v. Ashcroft, 336 F.3d 128, 137 (2d Cir.2003) (internal citations omitted).

Even construing, as we must, all the facts in Mass’s favor, the record confirms that his claims fail as a matter of law. As a general rule, it is “axiomatic that in order to establish a sex-based hostile work environment under Title VII, a plaintiff must demonstrate that the conduct occurred because of [his] sex.” Alfano v. Costello, 294 F.3d 365, 374 (2d Cir.2002); accord Brown v. Henderson, 257 F.3d 246, 252 (2d Cir.2001) (citing Oncale v. Sundowner Offshore Servs., Inc., 523 U.S. 75, 79-80, 118 S.Ct. 998, 140 L.Ed.2d 201 (1998)). To do so, a plaintiff must present, at a minimum, circumstantial evidence from which a discriminatory intent can be inferred. See Schiano v. Quality Payroll Systems, Inc., 445 F.3d 597, 603 (2d Cir.2006) (internal quotations omitted). Here, although the record evidences a wholly inappropriate work environment, Mass fails to present any facts suggesting that the sexual activities occurred because of his gender, or that Equinox’s alleged failure to respond to those activities — or to otherwise prohibit their occurrence— stemmed from a discriminatory intent. Accordingly, Mass’s hostile work environment claim fails as a matter of law, and, consequently, so do his remaining claims. See Pennsylvania State Police v. Suders, 542 U.S. 129, 143, 124 S.Ct. 2342, 159 L.Ed.2d 204 (2004) (where an alleged constructive discharge results from a hostile work environment, plaintiff must establish the latter in order to pursue a claim for the former); Cruz v. Coach Stores, Inc., 202 F.3d 560, 565 n. 1 (2d Cir.2000) (“Our consideration of claims brought under the state and city human rights laws parallels the analysis in Title VII claims.”).

We have considered all of Mass’s claims of error and determined them to be without merit. Therefore, there is no basis on which to challenge the judgment of the district court.

For the foregoing reasons, the judgment of the district court is hereby AFFIRMED. 
      
      . Alex Mass filed the instant notice of appeal along with Jaisiin Bethea, Freddie Gonzalez, Jason Guishard, Omar Harris, and Rodney Vanterpool, all of whom were Plaintiffs in the district court proceedings. However, only Mass filed a brief in this Court, which the other Plaintiffs did not join. As a result, this Court ordered the other Plaintiffs to show cause why their appeal should not be dismissed based on their failure to file a brief; those Plaintiffs did not respond to that order. Accordingly, we dismiss the appeal as to those Plaintiffs for failure to prosecute. See Fed. R.App. P. 3(a)(2) ("An appellant's failure to take any step other than the timely filing of a notice of appeal ... is ground ... for the court of appeals to act as it considers appropriate, including dismissing the appeal.”). Additionally, to the extent Mass attempts to assert claims on appeal on behalf of those other Plaintiffs, he is barred from doing so because he is a non-attorney. See 28 U.S.C. § 1654; Cheung v. Youth Orchestra Found., 906 F.2d 59, 61 (2d Cir.1990).
