How long does it take for a guy to be erected?

I would say not very long but it really depends on the guy! Like it only takes me a couple minutes if she's a good kisser and if its really passionate!!

For some guys it won't happen at all from a kiss. But for other guys, if the kiss is really good, it can be as fast as 30 seconds.

It depends on age and physical conditioning. If a guy is older and let's say smokes, it may be a while, as appose to a 18 year old athletic guy which can happen is 10 seconds. I am 42 and it would take me maybe 30 seconds to get fully erect. Kissing will usually do it for me and also if the relationship is new, it is quicker.

Lol depends if the kissing is really good and if she is touching it at the same time or if we are touching her, but if she lets us touch her in her private places then it won't take long :D

Umm it varies how the kissing is.

Well, depends on each man, sometimes just thinking to kiss the girl or hug her makes you erected.
