You are not alone in this situation. But in my case, I'm not trying to start another relationship since I believe I'm going to find it hard trusting someone again. So what's the point? My first experience wasn't that great. She would do the exact things she would warn me not to do. I don't cheat in the first place because I'm not a cheater. And like you said, I'm also scared of catching an STD and all that. Somewhere along the line, I started having this feeling that my girlfriend was not giving out 100% in the relationship like she wants me to. Sure enough, I found out from a Powerful Psychic that she was hiding stuffs from me. Although it took a lot of effort from a Psychic, plus my personal investigations to come to a conclusion, she still denied all facts to my face even after infecting me with an STD; something I've always been cautious of. This is what really scared me to the point where I asked myself if this really is the Love they talk about. Maybe, one need not rush and search, but wait to see if that special someone will come in the scene one day.
