Nope.
Romance is not sex, for a start.
But some societies use romance as a tool to foster or promote sexuality.
If two men are publicly romantic, they would be considered homoSEXUAL, and may even be attacked for that. So there is some connection between romance and sex, where I live.
Romantic relationships are unique because they are one of the few relationships where sex is not punishable. A man usually can't have sex with a bud, pet, or a family member; but he can have sex with a girlfriend or wife. So romance and romantic relationships are unique and distinct for their sexual feature.
When I was quitting pornography, some websites have told me to refrain from romance novels and romantic content. Again, there seems to be some implications there that further suggest a connection between romance and sex.
I will tell you right now that I would not be as antisexual if I were indulging in romance like in my past. I might not even still be a virgin if I was still indulging in romance like in my past.
Where I live, romance is somewhat associated with marriage or boyfriend-girlfriend relationships. Both relationships either legally or traditionally restrict sexual activity, where I live. But why? Why do those relationships restrict sexual activity? Why can't a girlfriend have multiple boyfriends? I wouldn't care if I had a girlfriend with multiple boyfriends. Again, it's a very strange sexual restriction that further proves an association between sex and romance. If romance and sex were truly independent, then why do romantic relationship require sexual restrictions for partners?
Where I live, marriage is sealed with a kiss. A kiss is sexual, even because two men kissing would be considered homosexuals and would likely be attacked for that. Kissing can spread Syphilis and other diseases via saliva. I can not kiss a wife without her husband being angry at me. Forced kissing can be considered sexual harassment or sexual assault. So marriage, which I consider the peak of romance, is now known to be sexual where I live and that discovery has greatly depressed me.
When a man is in a relationship where he is not allowed to be sexual with any other women than his wife or girlfriend, such restriction puts a lot of sexual pressure on him. Unlike before where he could just sexually engage with any lady he met, he has to refrain and bottle up that sexual tension, and likely release it all on his wife. there are some societies that foster and allow a pro-sexual environment, further pressuring a man to have sex. All of this pressure is then directed towards his wife. What happens when a man is daily overwhelmed with a lot of sexuality, but can not release that sexuality towards any other lady but his wife? I have not heard of a marriage where the couple did not have sex, where I live. Or what if his wife says "no sex tonight?" I will tell you that I have heard of marital rape though.
You can believe that there is no connection between romance and sex, but I promise you that there are a lot of romantic men who behave sexually. That might not be a coincidence. I can probably also say that there are a lot of older virgins and celibates, even I, who are not romantic or that don't engage in romance. That might not be a coincidence either.
Believe what you want to believe, but examine both the romantic and non-romantic man, and then tell me which one acts more sexual. I am not an idiot and will not be snared by romance to then grow any sentiment towards sex. I hate sex.
