No, traffic exchange is bad for your site. don't use it. Because the two websites who exchange there traffic don't belong to same niche. In this case both of you will loose traffic without any action. Secondly Search Engines don't like it. So, I would suggest you only go with one way linking.

Traffic exchanges from my experience really don't help with SEO.

Google will never rank websites containing explicit terms at the top. It has a policy and will not allow such websites to be browsed by the kids. So, even if the use of such terms were unintentional, the ranking of the website is bound to fall.try http://gigcrate.com/ for seo help

To the best of my knowledge, it is not recommended.
