We extract the Boer-Mulders functions of valence and sea quarks in the proton from unpolarized p+D Drell-Yan data measured by the FNAL E866 Collaboration. Using these Boer-Mulders functions, we calculate the cos2{phi} asymmetries in unpolarized pp Drell-Yan processes, both for the FNAL E866/NuSea and the BNL Relativistic Heavy Ion Collider experiments. We also estimate the cos2{phi} asymmetries in the unpolarized pp Drell-Yan processes at GSI.
