Hi guys, I'm new to this forum and in need of some psychological help, although flaming and random comments at my expense are well-deserved and appreciated 
Background:
I grew up in a Christian home and was taught that sex and virtually everything else was evil. Over the past couple years I have slowly been overhauling my beliefs, ranging from money to substances to sex. The problem is, after 23 years of cock blocking myself it's extremely difficult to close. A couple years ago I would stop during kissing, now I can't even get to kissing. I feel like my confidence is slowly draining away and I'm desperate to regain control.
Example:
Last night I had a girl laughing and initiating contact with me, but rather than reciprocating and Escalating Kino, I became extremely passive. After a couple minutes of avoiding/breaking eye contact, withdrawing socially and ignoring her in general, she left in search of another guy.
Problem/Rant:
This is so frustrating. I've always been confident in social situations and have no problem with the early stages. The problem is I can't figure out how to overcome my childhood conditioning to get physical (I've been turning down sex/groping/kissing since 7th grade and have become annoying comfortable doing so).
PS - I don't usually ask questions on forums because I tend to get fortune cookie advice in return (aka "just touch her" - thanks Sherlock, but that's what I'm having trouble doing). This is a real problem and amidst the virgin mocking I'm hoping to get a few useful answers. I've already read the kiss-close post ( fack another failed kiss close ), but I think I'm hung up one stage earlier. My withdrawal tends to follow a pattern, so I'm going to share what generally happens.
Pattern:
1. Find a target
2. Initiate conversation, get her to start laughing
3. Start basic kino (friendly - not romantic)
4. Assert authority over interaction (suggest activities/increase conversation value)
5. She starts physical flirtation (playful kicks, touching my back/shoulders/arms, looking into my eyes, increases physical proximity)
6. I sense ioi's and know I should reciprocate/escalate (kino/kissing)
7. Abstinence habit kicks in. I break eye contact, stop touching, withdraw socially
8. She gets confused and eventually moves on to someone more interesting
9. I feel miserable. My confidence sinks a bit and I feel like the habit is only gaining strength
Need:
I know I should "just do it," but I keep getting stuck up on what exactly to do. I would love a couple simple ways I can touch her that show interest and escalate the touching. I suppose what I'm asking for is the equivalent of a "canned opener" to initiate pre-kiss contact.
PS - Sorry for the silly question. I know it's basic but I've been trying for a while now and keep failing. Hopefully you guys can help. Thanks!
