I can’t climax

So I’ve been seeing my guy for about 3 months. Previously in the past I’ve always had trouble climaxing with a partner. Only one guy I’ve been with could actually get me to consistently, we dated for 2 1/2 years. Now I’m seeing someone else and no matter what we try I can’t climax. We’ve tried toys and everything. I don’t know if I’m just not comfortable or something subconsciously is going on. I’ll either get over sensitive or get annoyed and turned off by being so frustrated. I need advice. Also he recently found my g-spot and it feels like I’m going to pee when he it’s it while fingering me. Does that mean I’m going to squirt? And how would I do that? Never felt that sensation before. I don’t want him to get frustrated he can’t get me to climax and end things because he feels inadequate.

Please help with any advice about these 2 issues. Thanks ladies
