For this reason, we suppose both men and women odds of with got the original intimate experience with more mature lovers might possibly be large having participants you to definitely started the sex-life prior to

Look hypothesis 2: years preferences of males are needed to switch as a result of the mating means acted. Thus, we imagine distinctions to help you occur whenever pinpointing by the variety of matchmaking centered toward spouse during the initial intercourse. A whole lot more especially, on one side, the likelihood of having got earliest sex having an older woman (versus. an exact same-many years companion) would-be lower when having had basic sex for the own partner (proxy for very long-term matching) than just with a stranger (proxy to possess quick-title coordinating). Additionally, a high probability of with got first intercourse with a young companion than that have an exact same-many years spouse just in case you mutual which experience with the girlfriends unlike a complete stranger Footnote step 1 .

Lookup hypothesis step three: an effective matchmaking is expected to-be ranging from partners’ decades distinctions and age to start with gender. Considering the high share of women involved in more mature people, we including questioned highest potential compared to those of men.

Studies and techniques

The study old gaps anywhere between earliest gender couples depends toward SELFY (Sexual and you may Mental Life of Youngsters) survey done in the initial 50 % of 2017 inside 28 Italian universities, one on it 8094 young people, aged between 18 and you will twenty six, browsing undergraduate courses in economics and you will statistics.
