I'm the guy that failed English class twice in high school because I struggle with expressive language and using the correct words to convey the purpose of the essay or novel. So words are the biggest barrier to sexual tension. I have no idea how people on FB respond within 30sec-2min. It takes me on average 5-10 minutes to write a response that is interesting or funny.
BUT looks and workout do substitute.
Basically this is me: I can do anything in regards to improving myself, EXCEPT sexual tension related to words.
