18 year old guy without sexual experience

Hi, I'm 18 yrs old without any sexual experience or without girlfriend, I was born with a cleft pallet but since surgery it has been barely noticible and I am fairly muscled since do some excersice and lift weights, but I have never had any experience while havin a 5.5 to 6.5 inch penis.... It's small, and I have read that knowin how to please makes size look different, but I have no experience!!! I feel doomed,,,, am I hopeless or should I start watching porn(joke)?
