If you are looking at this woman as a potential long term partner wife , etc remember to take the long view . Good sex is important , but in the scheme of things you spend only a tiny portion of you life having sex , even if you do it a lot . Mindblowing sex will NEVER make up for a marginal relationship outside of your bedroom . It can for a while , but it won ' t take long before the cost becomes too high . When my kids have asked me about what I thought of potential GF ' s or BF ' s , I always asked them if they felt they could stay with them if tomorrow that girl showed up paralyzed and in a wheelchair . And would the girl likely stay with you if the reverse were true . If you can ' t honestly say yes , then move on . It can take time to get attuned to each other . That grass is always greener thing could be at work , remember there is a reason that your former GF is a FORMER GF , in spite of the awesome sex . Weigh all the factors , decide what you want from this relationship , and choose carefully . Old guy , married to the same woman for 33 years , sex is still way fun .
