“…As research results often point out the fact that attitudes toward sexuality are associated to sexual behavior (Lefkowitz et al, 2004;Luquis et al, 2012;Nikken & Graaf, 2013;Weeden & Sabini, 2007), solitary and dyadic sexual desires might be also related to specific sexual attitudes as well as to trajectories of partnerships. For instance, solitary sexual desire and activities are perceived as positive by some individuals, while for others, they are perceived as negative or even shameful sexual activities (Carvalheira & Leal, 2013;Costa, 2012;Davidson & Moore, 1994;Gerressu et al, 2008;Jaspard, 2005;Kaestle & Allen, 2011). Therefore, we expect that individuals who have developed intimate trajectories characterized by numerous partnerships facilitating permissive attitudes toward sexuality have greater solitary and dyadic desires, while those with few partnerships, which supposedly are associated with more conservative attitudes toward sexuality, might have lower solitary and dyadic desires.…”
