Slickaz, in my opinion try the LTR and see if it's for you. A couple years ago my relationship life was nothing more than hooking up with random girls. I used to make fun of guys who were in LTRs. It was always lots of fun and my friends and I have great memories from those days, but it was always lacking. At the moment I'm in a LTR with a girl who lives overseas and we are deciding how to proceed with our future together right now. I can honestly say that no matter what happens it was the best decision of my life to get involved in the LTR. You will grow as a person, you cant grow as a person by having lots of sex with random girls. You will have a lot of fun and your sex life will grow, but you probably wont grow as a person. I'm in no way offending this lifestyle if thats what you choose because I used to be the same. And I'm not trying to preach. Its just my opinion. Just do what feels right. But dont turn down the possibility of the LTR if you're concerned about missing out on sex with other girls. If it doesnt work out you can always return to that, and you'll be the wiser for it. But you may not be able to go back with this girl down the track. Goodluck
And to answer your question which was the whole point of your post, is sex too easily available, that really depends on alot of things. I've found it depends on location and current lifestyle mostly. When I was travelling I found that certain countries (especially Brazil and the USA) girls on AVERAGE were easier to have sex with than in other countries such as Argentina. This is just my personal opinion/experience. Also, further into location, I found that in active places (beach resorts, college campuses) sex was readily available, as opposed to say a small town. This is common sense. Also your lifestyle, if you're on holidays or living in a college or partying alot or whatever, then sex may seem readily available. But for people who have busy lives, work 9-5 and have lots of responsibilities etc it may be more difficult. But in the end it comes down to the individual.
