ok heres the issue, a perfect example of good guy's finishing last. Whenever i have sex with my gf i always concentrate on gettin her off because 1. im a nice bf and 2. shes to lazy to do much for me. Now as most guys would know the effort to get a chick to cum can be quite extensive and tiresome (i have no problem doin this as i like to pleasure my gf thogh) now here is where the problem occurs. since my gf gets little stimulation from intercourse alot of our sex is concertrated around stimulatin the clit. overall at the end of sex it results in me being too tired to cum myself, unsatisfied as intercourse was not enough as well as havin a gf to lazy with not enough energy to make me cum herself. evidently 'sex' is becomin more and more boring, i get more pleasure form masturbating. Is there any way to fix this problem?
