The direct contact makes for a better feeling for many and more so at the end semen causes a chemical reaction in women that tends to cause a more satisfying or even elevated experience. It also adds a level of intimacy being unprotected. Plenty of people do feel this way. Guys that get off from constriction, and guys that get off from friction. I want it all. The lack of the chemicals being released can make your brain associate a loss of pleasure, as well as it can affect your sex drive and even cause depression, same as quitting most drugs or chemicals would do to you. That's my theoretical standpoint. Plus, cumming inside her is incredibly sexy. Could my husband be pleasured by my mouth through a condom? Couples should practice birth control if they do not want a baby. Exploring with my mouth is the whole point. Sex is fucking fun…what can I say? Two different kinds of guys. If you're not, those condoms are just birth control, and birth control comes in many forms. To wear a condom is to rob me of pleasure, to keep me from enjoying the fruits of my labor, to stop short of sharing every drop of himself with me. Sperm has been shown to cause a release of chemical such as endorphins, estrone, prolactin, oxytocin, thyrotropin-releasing hormone, and serotonin, which can cause higher senses of pleasure and also connectivity with your partner.
