Anal w/ guys

I love the feeling of sticking things up my asshole. Im still a virgin. Im straight, but I want to know what it feels like to have a real dick up my ass.

1. The main question is how easily will I get an STD/STI if I were to get anal from another guy? Preferably with a condom on.

2. Also how likely would it be for me to get an STD/STI if I were the one sticking my P in another guy's anus, while whereing a condom?

3. Will it cause damage to my anus?

I have no experience and very little knowledge on this subject. Best i have done is stick a banana up my anus using coconut oil as lube. Im also 19, if that changes anything. So dont be vague with the answers, thank you.
