Venting... Maybe I'm just weird...

I swear I don't try to laugh, but I am hypersensitive to touch, and dear lord anytime my bf gets near my neck I burst out laughing completely killing the mood. ? It's begining to take it's toll in me. I hate that I can't receive any foreplay because all my nerves want to act haywire. I have found that if I instigate things, it's not as bad. It seems to only flare when he starts getting super affectionate with me. It's to the point that he asks me if I want have sex, just so that I can brace myself for him to start touching me. Le sigh... It's so cumbersome. All I really want is to enjoy him kissing every part of me without bursting out into fits of uncontrollable laughter.
