Anonymous2: unattractive and unsuccessful African there's a canon comic where Deadpool concocts a plan to get Cap America to sit on his lap. Then there's all the ho yay with Cable and Spidey. At the very least, DP's bisexual.
Anonymous5: its been canonically confirmed that Deadpool is in fact pansexual, which sexual attraction to all genders. I mean, its been pretty obvious he's LGBT+ in the comics, cross dressing, heavy flirting with spiderman, wolverine, and more. Also it's been hinted that he and Cable were in a sexual relationship at one point in time.

tl;dr: Gay? no. Into men? Yes, it's canon.
