It's not you honey, trust me. Its him.
I'd say its BOTH.See,its about the partner and the CHOICE in partners. There is 1 way of having guaranteed pleasurable sex and that is to get to know your partner LONG BEFORE you have sex and to know YOURSELF and what pleases YOU even before that.
Chose to have sex with someone who has demonstrated unwavering care and true desire to get to know EVERYTHING about you LONG before you have sex(a great lover isn't necessarily someone with experience,just someone who truelly cares and would be deligent in learning,showing and exploring ways to please).
Choose someone who WANTS to learn and show you in EVERY way how much they care and wish to please you. Choose someone who chooses YOU and not any other.Choose someone who meets a long list of qualites YOU want, need and believe will make a great mate and healthy,functioning, long lasting relationship. Chose someone who is OPEN and HONEST and communicates well. Choose someone who is affectionate regardless of the promise of sex.
Choose someone you love and loves you back,who gives back and gives 1st.
Find these things and you'll have no problem whatsoever. Find these things and you'll find magic! You'll find a RARE find! Something few ever find. You'll also find guaranteed PLEASURE
