Sex and affection

Sex and affection can be subjective for some people. When every people do sex they show affection? or is a "mecanic behavior"? For monogamous gay men that have a partner affection is very important in a relationship because is one sign of show to their partner that they love.
Affection is you feel attracted for your partner and you feel that you need him and feel that you want your partner close of you. Affection is like kiss your partner or send sign that you like him.
For guys that are "easy" and only prefer the easy things like do sex without commitment, use and next leave etc... these guys when they do sex they think that they show affection but of course is not truth. They of course can "like" this person but when they do sex with that person what they only want is get most pleasure possible and satisfy their "instints". They have what is called "mecanic behavior" and this is about being sexaholic that they use people like object that play and after they stay bored they look for other "object".
For monogamous and gay men, no, affection in sex is very important like kiss many times the partner, say beautiful or hot (In the good sense without been dirty) words, touch all body and stay close as possible. In "easy" guys no, they do sex and of course they kiss their partner but is in a "cold" way.
